Question

Evaluate: 10 + 8 ÷ 2 - 4

Answer 1

I thought it was 5 but when I looked it up it said it was 10 so idk

Answer 2

you need to use order of operations

are you familiar with PEMDAS?

Answer 3

Pemdas,

10 + 4 - 4

4 - 4 = 0

So your just left with 10

Answer 4

Yeah parentheses exponents multiplication division and subtraction but nothing was in parentheses in this problem

Answer 5

lol what @tHe_FiZiCx99 said

since division comes first, you divide 8/2 which gives you 4

from there, it's all + and -

soooo you just combine :)

10+4-4=14-4=10 :)

Answer 6

yes you have that right... but division was in there... so you had to do that first. does that make sense?

Answer 7

P - Parenthesis
E - Exponents
M - Multiplication
D - Division
A - Addition
S - subtraction


Doesn't matter, division came first then just add them, 10 + 4 - 4

14 - 4 still equal's 10 :)

Answer 8

So I made a mistake adding 10+8 I was supposed to do the whole thing in the order of PEMDAS and divide 8/2 first?

Answer 9

Yes

Answer 10

yes the whole point of pemdas is to do it in order :)
