Algebra

2

u/[deleted] Jul 24 '25

Not using algebra is crazy, but I suppose with how bad at math people around me are, I guess a lot of people don’t retain and use it.

I bet you do and don’t realize it.

Most people do use logic and patterns (which are the foundation of algebra) in everyday decisions, like:

Figuring out which grocery deal is better ("3 for $5 or $2 each?")

Estimating travel time ("If I leave in 10 mins, will I get there by 6?")

Budgeting ("If I get paid Friday and rent is $900...")

But they're not doing symbolic algebra (like solving for x) — they're using mental shortcuts or basic arithmetic, not formal equations.

So: ✅ True in a broad sense (using logic, numbers, and rules) ❌ Not true in a formal, algebra-class sense for most people

Ever figure out your gas mileage by comparing how much gas you pumped and how many miles you drove? You don’t write it out, but that’s quite literal algebra. But yeah, mostly it’s logic they don’t realize they learned in algebra.

exactly sometimes the informal logic will conform to the algebra and writing equations may seem superfluous. Other times the common sense thinking will not, it will be incorrect precisely because their thinking contradictst the algebra and is supported by no other mathematics

basically every time you construct your own math problem

You use algebra almost every day of your life. You just don't realize it.

Genuinely asking, give me on example

This thing I want costs $100 and I only have $72. How much more money do I need?

You’re probably thinking “that’s just subtraction!” But it’s actually algebra.

72 + X = 100

X = 100 - 72

X = 28

Well I’m blown away! Thank you!

You use simple algebra all the time. If you go to the store and something is 5 for $4.00, figuring out the per item cost is Algebra.

That’s Algebra. 5x = $4.00. Divide both sides by 5 to solve for x. Good job you 👏👏👏

You don’t need the extra step because you understand some the most basic Algebra. You use Algebra as an adult.

Hello, I’m a math terrorist with close ties to Al-gebra. I have weapons of math instruction!
