Calculus III (Multivariable)
Calculus III extends single-variable calculus to functions of several variables, introducing vector calculus and the geometry of higher-dimensional spaces.
Calculus III extends single-variable calculus to functions of several variables, introducing vector calculus and the geometry of higher-dimensional spaces.
Calculus II builds on the techniques of integration and introduces infinite processes like sequences and series.
Introductory Calculus (often called Calculus I or AP Calculus) is the mathematics of change. It formalizes the concepts of instantaneous rate of change and accumulation.
Algebra II extends and deepens the concepts from Algebra I, introducing new types of functions and more sophisticated problem-solving tools.
Geometry is the study of shapes, sizes, positions, and properties of space. It develops logical reasoning through formal proofs.
Algebra I is the foundation of all higher mathematics. It introduces the language of mathematics through variables, expressions, and equations.
A typical American high school mathematics progression:
It's the tail end of June here in Spokane, and we're finally getting that dry Inland Northwest heat — the kind that makes you grateful for a jobsite with any shade at all. Summer 2026 is here, and if you're in the trades like me, you're probably running faster than you'd like and still playing catch-up.
But here's what's been eating at me. Every time I turn around this year, something costs more. Lumber. Copper. PVC. Fittings. According to the Associated Builders and Contractors' report a couple weeks back, construction materials were up nearly 10% year over year as of May. Ten percent. You feel that in your bids, your margins, that knot in your stomach when a job you quoted in March suddenly costs more to finish than you figured. And with the industry short nearly half a million skilled workers, good help is harder to find than ever. Every dollar and every hour counts more than it did last season.
So I started looking hard at where my money and time were going — and I had to get honest with myself about something I'd been avoiding for years.
When I started my business out of my truck, I did what everybody does: wore every hat. Estimator. Bookkeeper. Accounts receivable. Marketing director. Web designer.
That last one nearly sank me.
I spent three weekends building my own website. Watched tutorials, picked a template, made it look halfway decent on my laptop. Then I got busy — you know, doing actual paying work — and that site sat untouched for over a year. My portfolio still showed a job from 2023. My services page was missing half of what I offer. And on a phone? Let's just say it looked like something my kid made in computer class. Text overlapping images. Buttons that didn't work. The whole deal.
Then a homeowner told me straight up she almost didn't call because my website looked like I might've gone out of business. That stung worse than any punch list revision ever did.
We've got work. Plenty of it. But the big outfits with their polished websites and search ads are scooping up the easy leads before most of us even know they're out there. When a homeowner searches for a contractor on their phone, they're making a call in seconds. If your site loads slow, looks clunky, or was clearly built in an afternoon five years ago, they scroll to the next name — even if you'd do better work at a fairer price. That's just how it works now.
In Spokane, that's even more true. We're seeing more people move here from the west side every year — folks who don't have a regular guy yet. They're Googling. Checking reviews. Looking at your site before they ever pick up the phone. And with the North Spokane Corridor shifting traffic patterns and new subdivisions going up all over the valley, the competition for those customers is only getting tighter. First impressions matter more than they used to, and a bad website is a noose around your neck.
I finally did what I should've done years ago: I stopped pretending to be a web designer and focused on what I actually know how to do. I found codelamar.com, which builds website kits specifically for tradespeople — plumbers, electricians, roofers, guys like us. Not a generic template you wrestle with. Something built for a contracting business from the ground up. Took me an afternoon to set up, and for the first time in years, my website doesn't embarrass me. It loads fast, works on a phone, and tells people what they need to know: who I am, what I do, and how to call me.
Since then, I've picked up at least four jobs that started with a customer saying, "I found you online and your site looked professional." Four jobs. That's real money. That's the difference between a site that works for you and one that works against you.
I'm not saying a website fixes everything. Materials are still volatile. Labor is still tight. You'll still have that one client who takes three weeks to pay a net-15 invoice, and you'll still have to deal with the endless paperwork that comes with running a small business. But if your online presence is working against you instead of for you, that's a problem you can fix right now — without learning to code or spending a fortune you don't have.
Summer's short in Eastern Washington. The sun's out, the days are long, and there's real work to do. Don't spend another weekend wrestling with a site builder when you could be with your family or just catching your breath between jobs.
Let somebody else handle the pixels. You've got a business to run.
You know what's funny about running a trades business? We'll spend $50,000 on a new truck without blinking, but ask us to invest in a website and suddenly we're counting every penny like it's coming out of our own pocket (which, let's be honest, it usually is).
I'm sitting here in my office in Spokane, looking out at another February morning where the weather can't make up its mind, and thinking about how much our industry has changed. Just last week, I was talking to my buddy Mike over at Mikes Plumbing & Heating, and he told me something that stopped me in my tracks. He said, "You know, I used to get 80% of my jobs from word-of-mouth. Now it's closer to 30%."
And honestly? That's exactly what the latest small business data is showing us. According to that February 2026 Small Business Now report, 68% of us small business owners are actually planning to increase our marketing budgets this year, even though inflation is still chewing through our profits like a hungry beaver. We're finally getting it — you can't just wait for the phone to ring anymore.
Look, I get it. We wear about ten different hats on any given day. You're the plumber, the bookkeeper, the scheduler, the parts runner, and somehow you're supposed to be a marketing genius too? The construction industry alone needs nearly half a million new workers next year, according to the latest forecasts. We're all stretched thinner than drywall mud, and something's gotta give.
Here's the thing though — that digital storefront you've been putting off? It's working 24/7, even when you're crawling under a house at 10 PM trying to fix a burst pipe (because that's apparently when pipes decide to burst in Spokane winters). Your website doesn't complain about overtime, doesn't need coffee breaks, and doesn't ask for benefits.
Let me guess your daily struggle: you wake up to 47 emails, half of them are spam, and the other half are people asking "how much for..." without giving you enough information to even ballpark a quote. You spend half your day chasing down details and the other half actually doing the work you're supposed to be doing.
Then there's the credibility game. You know how it goes — you show up to give a quote, and the homeowner has already looked up three other contractors on their phone while you were driving over. They've seen slick websites, glowing reviews, and professional photos. And then there's you, with your business card that's been in your wallet since 2018 and a Facebook page that still has your logo from two business names ago.
I'm not saying you need a website that looks like it was designed by some Silicon Valley startup that burns through venture capital like we burn through drill bits. But you do need something that tells potential customers you're legit, you're local, and you actually know what you're doing.
Think about it this way: when was the last time YOU looked up a service online and chose the business with no website, no reviews, and nothing but a phone number from 2015? Exactly. We expect more from other businesses, so why wouldn't our customers expect more from us?
The folks over at codelamar.com get this — they're building website kits specifically for trades guys like us. No fluff, no complicated stuff you need a computer science degree to understand. Just clean, professional sites that make you look like you've got your act together (even if your truck is currently serving as a mobile storage unit for three different jobs).
And here's the really cool part: a good website actually filters out the tire kickers. When people can see your services, your service area, examples of your work, and maybe even some testimonials from that nice family over by Manito Park, they're already halfway sold before they ever pick up the phone.
Sure, you can keep relying on word-of-mouth and hoping that your cousin's friend needs their bathroom remodeled. Or you can wake up to actual qualified leads in your email inbox — people who already know you do electrical work in Spokane Valley, they've seen your photos, and they're ready to book.
The construction boom is still going strong, with nonresidential construction hitting nearly $62 billion in December 2025. There's plenty of work out there — but you've gotta be findable to get your piece of it.
Look, I'm not gonna sugarcoat it. Running a trades business is tough. The hours are long, the physical wear and tear is real, and some days it feels like you're just treading water between invoicing, scheduling, and actually doing the work. But having a professional web presence? That's one thing that actually makes your life easier, not harder.
So here's my challenge to you: spend one less hour this week scrolling through Facebook and figure out what you want your digital storefront to look like. Your future self — the one who isn't answering "how much for..." texts at 11 PM — will thank you for it.
Now if you'll excuse me, I think I just got a text about a water heater emergency. Some things never change, right?
February 2026, and if you're like me, you're probably juggling three jobs while trying to remember if you sent that invoice from January. The construction world is buzzing with news that we'll need nearly 350,000 new workers this year, but honestly? Most days I'm just trying to find time to return phone calls between jobs.
Let's be real – running a small trade business isn't exactly glamorous. One minute you're crawling under a sink fixing a leak that's been "slow" for three months, the next you're playing accountant, marketer, and customer service rep all before lunch. And don't get me started on chasing down payments. I swear, some clients treat their 30-day terms like gentle suggestions rather than actual deadlines.
But here's the thing – while we're busy keeping the lights on and water flowing, the bigger companies are playing a different game. They've got slick websites, online booking systems, and they show up first when someone's Googling "emergency plumber near me" at 2 AM. And let's face it, when someone's basement is flooding, they're calling the first name that pops up, not necessarily the best plumber.
The marketing landscape for trades has shifted dramatically in 2026. I was reading the other day about how AI search and online booking are becoming the new standard. Customers expect to text you, book appointments online, and see your work before they even pick up the phone. It's enough to make a guy want to go back to the days when word of mouth and a solid reputation were enough.
And honestly? That's where most of us small guys are dropping the ball. We're great at our craft – whether you're bending pipe, running wire, or fixing roofs – but when it comes to showing up online, we're invisible. Potential customers find our competitors first because they've got the digital presence that says "we're legitimate" even if their work isn't half as good as ours.
Think about it: when was the last time you hired someone without checking them out online first? Exactly. Your website isn't just a digital business card anymore – it's your first handshake, your portfolio, and your 24/7 salesperson all rolled into one.
A solid web presence does three things for us tradespeople:
Look, I get it. The thought of spending thousands on a fancy website makes me break out in hives too. That's money that could go toward a new tool van or that welding machine you've been eyeing.
But here's what I've learned: you don't need a massive custom build with all the bells and whistles. You need something professional that shows off your work, makes it easy for customers to contact you, and looks good on a phone (because that's where 90% of your customers are searching from).
That's actually why I ended up checking out codelamar.com – they've got website kits specifically built for trades guys like us. No confusing tech jargon, no features we'll never use, just straightforward sites that help us get found and look professional. Sometimes it's worth letting someone else handle the stuff we're not good at, you know?
Between the labor shortages everyone's talking about and the fact that customers are getting pickier about who they hire, having a solid online presence isn't optional anymore. It's as essential as having reliable tools and a good work truck.
The good news? You don't have to do it all yourself. Focus on what you do best – the actual work that keeps this country running – and let someone who understands our world handle the digital stuff. Your future self (and your bank account) will thank you.
Now if you'll excuse me, I've got a leaky faucet to fix and about a dozen follow-up calls to make. Such is the life of a tradesman in 2026, right?
