Yeah, now calculate 6% of 36
Edit: Replies itt make me believe that everyone on Lemmy is a chatbot
6x3x10 + 6x6, move decimal point 2 places to the left
I'm a Maths teacher :-)
Wow, that's nice! I like it.
I just hope that you are not starting grading your students with the phrase "You're absolutely right!"
It's called grouping. It's part of the curriculum here. Break the arithmetic into easily calculated groups.
I'm not in the U.S. no. We still require teachers to be qualified here (Masters)! 😂
Bout tree fiddy
6% of 36 is 0.06 * 6². 6³ = 216 so 2.16
1% of 36 is .36, and .36 * 6 = 2.16. I'm a fan of this method most of the time, though the one in the OP is good for some math problems.
36% of 6 is roughly 33.(3)% of 6 which is 2.
3% of 6 is .18 so about 2.18
I usualy get the value of 1% and then multiple that back to original, so:
1% of 36 is 0.36 (just move 2 spaces) and thats times 6 which is 2.16
3.6/2+0.36 = 2.16
(10% of 36 halved, so 5%, plus 1% of 36)
