This is a question about my math homework! Please help! quiz tomorrow!
PEMDAS first. Makes sure you are following the rules of PEMDAS which states that division should be done before addition.
So let's look at each of the division in the problem.
32/-2 =
-25/5 =
When you are dividing or multiplying by a negative number, there are rules.
A -number times/divide a +number will result in a -answer. (-2*+2 = -4) or ( 4/ -2 = -2)
A -number times/divide a -number will result in a + answer. (-2* -2 = +4) or (-4/-2 = +2)
Therefor in our problem:
32/-2 = - 8
-25/5 = - 5
Since we are adding in the original problem, anytime your signs are the same, just combine the numbers. In this case, both numbers are negative, just use the negative sign and combine.
