I'm not sure that I understand the point of your meme.
Do you find the second way too hard?
Unlike the left, I prefer children learn math, reading, and writing as well as history.
So it was too hard for you.
That's the problem with the way you learned math. You learned to memorize things, but not understand them.
I always suspected that you were ******* stupid sans the ability for critical thinking........but you proved it by supporting "commie core". You strike me as the kind of idiot that would lay out ten pennies and have your "student" subtract six of them....and then chastise them for not doing it the "commie" math way. What the **** are you the "Doctor" of again? The "Doctor" of stupidity?
Math is indeed "math"....addition and subtraction doesn't change.......just because a group of children come to the agreement that six times six equals thirty-five doesn't make that the correct answer just because a consensus was reached, ya dumb ass.
Hand a cashier a ten dollar fiat federal reserve note for a three dollar and eighteen cent purchase and let me know if you would accept getting back five dollars and eighty two cents in change because the general consensus was correct to them...according to commie core?
The cash register should tell them the correct change. If it doesn't, they should use the method listed below.:
18 cents is two less than even dime, so they would give you 2 pennies.
20 cents (18+2) is 80 cents short of an even dollar, so you get back 80 cents, which would be three quarters and a nickel.
You are now up to 4 dollars, (3+ .18 + .02 + .80 = 4) so to get to ten dollars, your change would be 6 dollars, so they would give you a 5 dollar bill and a one. (3+ .18 + .02 + .80 + 6 = 10)
So your change is $6.82 (.02 + .80 + 6 = 6.82)
That is called the count-up method and predates Common Core by a couple of centuries.
