There are too many tards out there who can't make proper change, when you hand them a twenty o pay for something that costs $12.45. I've had dumbasses hand me back more than what I paid for a pizza with a $50.

Love all the old fuckers who seem to think this is only a young people problem.

Get over yourselves.

I'm a geezer whose basic math could improve.

I got a surprise when I started playing darts and found other people correcting my calculations. Same with golf. Mental arithmetic is potentially everywhere. Fluency with it enriches us in both senses.

I think darts at the Legion on Thursdays has helped my addition/subtraction skills.
3 digit subtraction and addition is second nature to me.

Exactly. And the same with me. I did well in math until about grade 10 then my ability to do well hit a plateau. But that’s just the way I am. I’m a memorizer and changing up equations on me just threw me for a loop.

I can still do all the essential math needed for day to day life. And so should everyone else. Saying your no good at math means that calculus and physics isn’t your thing; it doesn’t excuse you from being able to figure out how much tax you pay on groceries or making change or things like that.

Same. I was doing good in Math 13/23/33 in high school with around a 60-70% average mark. Then I got goaded into going into Math 30 and it just collapsed and wrecked my overall graduation average. Barely squeaked through with an even 50%. I could do some fairly basic trig and algebra without much difficulty but tossing in those tangents and arcs just ruined me. This is why I'm saying what I'm saying here. Don't put someone in something that's beyond them just so they can get crushed by finding out the hard way that it's not suitable for them. None of this Star Trek level fantasy crap where some people are actually saying shit like calculus should begin in Grade 6, and not just for the little psycho future STEM kids, but for everyone.

Ah cmon, Calculus isn't that bad

I formed a habit as a kid, whenever I (or the person I was with) would pay with cash for something, I'd see if I could figure out the change faster than the cashier could count it out.

People are incapable of math because they stop using it. Finding ways to incorporate it into your life keeps it fresh in your mind.

I remember hating it in Gr. 12. That was mainly due to the asshole who taught it than the actual material covered.
Another problem is the fact that kids don't or aren't required to memorize the multiplication tables. That helps when doing mental maths as you don't have to think about the multiplication....it's just there.

My Grade 13 Algebra teacher did 4 digit multiplication in his head.

Asshole.

He used to do 2 or 3 of those at the beginning of class, kids just give him
numbers, and he just exploded our heads.

My Grade 13 classes were Algebra, Trig, Calculus, and I forgot the other one,
maybe Statistics,

Accounting and Economics.

Couldn't agree more. They're justification is that memorization isn't learning the concept. But I was taught what the concept of multiplication is, and then provided with the tables to memorize it.

[ShepherdsDog]

We learned that multiplying was grouping first, circling four groups of five objects was 4x5. But, once we grasped the concept, memorizing the tables simplified things.

Fifty years after delivering a weekly paper that was 35c a month I can still multiply by 35 in my head... and I will never forget the old fat lady that smoked huge rollies and gave me a whole 50c tip one Christmas....
There's a lot of stuff you don't use, but you don't really lose. A quick Google these days and 'oh yeah - that's how it works, I remember now'

Asshole.

There was a time in University that I'd read a clock, and square root the time out of habit.

Really screwed me up at quarter past 3.





edit: Ok, you might not get that joke. 3:14 = Pi. Pi is irrational, so to actually find it's square root is impossible. Or 1.772, whichever came first.

Not as funny as it was back then.

Probably still doesn't.
