Question

For the problem 9 + 2(3) do you get the same final answer if you add first as you do if you multiply

first?

Answer 1

No

Explanation:

no you do not get the same answer

This is the order in which you should approach problems, doing otherwise may lead to a wrong answer

P - parenthesis -- meaning solve whatever is the the parenthesis

E - exponents -- an example of an exponent is
`2^(3)` which equals 8

MD - multiplication/division

AS - addition / subtraction

for our particular problem, we have

9 + 2(3)

multiplication trumps addition thus we perform multiplication first

9 + 6 = 15 ---CORRECT

if we were to addition first we would get

9 + 2(3) = 11(3) = 33 This would be WRONG

note: multiplication and division are on the same level

subtraction and addition are on the same level

if you encounter a problem like 4 ÷ 2 * 3. perform the calculation from left to right thus we would have 4 ÷ 2 = 2 and then 2 * 3 = 6

same applies for addition subtraction

Answer 2

no

if you add first you get 33
9+2(3)
11(3)
33

if you multiply first you get 15
9+2(3)
9+6
15

15 would be correct because multiplication comes first in pemdas :)
