Can someone correct these
(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..
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
