Can someone correct these
(1) -5^2-3
25-3
22

(2) The sum of m and n, divided by the difference of m and n.

My answer: (m+n)/ (m-n)

(3) The quotient when 3 more than a number is divided by 3 less than that same number

My answer: (x+3)/(x-3)

These are all correct..

Trish,
the one about -5^2-3
-5^2 isn't it -25 or it is 25

Just 25, because it's -5 times -5. A negative times a negative is a positive.

Just remember that with negative numbers that have exponents, if the exponent is even, it will be +, and if the exponent is odd, it will be -.

The quotient when 3 more than a number is divided by 3 less than that same number
