Yes it is right. Use BIDMAS

Bracket = (-3 + 2) = -1

Indices = (-1)^2 = 1

Division = none

Multiplication = 5 x 1 = 5

Addition = none

Subtraction = none

Answer = 5. - Jan 21st 2009, 08:30 PMkatchat64
5(-3+2)^2

Remember "Please Excuse My Dear Aunt Sally"

The P is for paranthesis

The E is for exponents

The M is for multiplication

The D is for division

The A is for addition

The S is for subtraction

The first thing you do is what is inside the parenthesis -3+2 which = -1

then ^2 the -1 and it is 1

and then multiply it by 5 which gives you an answer of

(5)(1)= 5

So your answer was correct! (Nod)
