What are the rules for adding integers with the same sign?
Add the integer values and apply the common sign. For example +5 and +7 : 5 + 7 = 12 so + 12 -5 and - 7: 5 + 7 = 12 so - 12
What is the fact family of 7 and 5?
7+5=12 5+7=12 12-5=7 12-7=5
Is 5 over 7 equivalent to 12 over 36?
no, they are not the same, 12/36 is larger 12/36 = 3/4 = 0.75 5/7 = 0.71
What is the sub set of 12 7 0 5?

How do you divide negatives?
The same way you divide positive exponents like ( x^-7 ) / ( x^-12) = x^( -7 - - 12) = x^( -7+12) = x^5
The difference of a negative integer and a positive integer is?
An integer that is equal in magnitude to the sum of their absolute values. Its sign is the same as which of the two numbers you are taking the difference from. For example, for the integers 5 and -7. Their absolute values are 5 and 7 so that the sum of the absolute values is 5+7 = 12. Then 5 - (-7) = +12 and -7 - 5 = -12.
