Youd be supriced how much simple everyday things use maths and you dont even notice. When you look at the speedometer and calculate im your head how long its going to take to arrive you are doing supricingly complex math. Add how much it will use gas and how far you can get with full tank.

Same when you compare two different sized packages of the same product and try to asses which one is more bang for your buck.

Or if you are trying to calculate is it legal to drive after night out now or should you wait for an hour.

After a weekend trip with your friends when you start to tally who brought what stuff and how expensive it was and who is the vegan who did not eat the steak but brought case of wine that everybody was drinking exept Steve who was the dedicated driver. Then there was Sarah who was only one night at the rented house while everybody else was there two nights, but she bought the steaks and other meat that the rest of the crew (not counting the vegan) ate the whole weekend.

Also almost anything done with building or renovations.

More closely you understand the calculations the less it becomes math and more to just how things work. Math is funny like that.

If we keep redefining maths to not include the bits of maths that are inconvenient to people’s arguments it all sort of becomes pointless.

A couple weeks ago I used pythagorean’s theorem to calculate the maximum size of tv my friend could buy to fit in their entertainment center based on the vertical space they had.

Every time I drive I’m mentally running through calculations on where each car around me is going to be based on their current speed, current acceleration/deceleration, and position relative to other vehicles that may cause a change in acceleration/deceleration. Having learned calculus that’s a lot more intuitive and easier to do than if I hadn’t.

I would be a less functional person if I had not learned anything beyond basic arithmetic.
