Follow the PEMDAS rule:
(solve equations in Parenthesis, exponenent, multiplication, division, addition, substraction in order)
Put this in an equation form first
7-3(6)/3
divide the 6 first with 3 so its 2
7-3(2)
multiply 3 and 2 so...6
then substract
7-6=1

first u solve the paranthesis
(27-21)=6
then u can write it as 7-(3*6)
i.e. 7-18 and then the entire thing
is divided by 3 so the final answer
is -11/3

7 - 81 + 63 = -11 and than -11/3

Ok! First you would distribute the -3 to 27
which would be -81, then distribute -3 to -21
which would be a positive 63
Bring down the 7
So it would look like
7-81+63 over 3
7-81+63 = -11
So your answer is -11
over 3

do the operation in the parenthesis first. when you do, youll get this:
7-3(6)/3
then do the 7-3 to get this:
4(6)/3
then multiply the 4 by the 6 to get this:
24/3
then divide:
youre answer is 8

7-3(27-21)/3
solve parenthesis first
7-3(6)/3
then subtract 3 from 7
4(6)/3
then multiply
24/3
then divide
