Math question...
 
What is 56 - 24 / 3 + 12?

My child's math teacher said 36.
I say 60, as does a friend who was formerly a schoolteacher.

Essentially, in PEMDAS, do you literally do all the operations according to P-E-M-D-A-S? So that all addition gets done before all subtraction? Or are addition/subtraction considered equivalent in priority so that you then do the equation left-to-right?

60.

PEMDAS applies.

Teacher needs to go back to school.

56 - 24 / 3 + 12 = 60

56 - (24 / 3 + 12) = 36

Yep, 60.

Tell her to show it to her teacher like this: 56-(24/3)+12=60.
Then tell her to ask her teacher where his/her degree was from. :D

Yes, there were no parentheses. The only difference was that I used the slash sign instead of the traditional division sign ('cause I don't know how to do that symbol on my iPad).

Just ask the teacher if

56-8+12 is the same as 56+12-8. Then tell her there are no parenthesis ie. 56-(8+12)

M.D. Holloway 10-30-2016 05:20 AM
well, there is the option of 56-24 over 3+12 or 32/15 0r 2.13...not saying its right but its another way!

wdfifteen 10-30-2016 05:26 AM
Again?

M.D. Holloway 10-30-2016 05:36 AM
56 - 24 / 3 + 12

(56-24) / (3+12)

56-24 = 32
3+12 = 15

32 / 15

2.13
