How to add, subtract, multiply, and divide rational numbers
By: Trevon Houston and Jackson Hudson

How to:

Add integers.

1. You want to find the absolute value of the two integers that you are adding

2.Add the absolute values if the two integers consist of the same sign

3.But if the signs are different you will have to subtract the two

4. for example -7 + 2 equals -2

Subtracting integers

1. First you want to find the absolute values of the two integers

2. Subtract normally if the signs are the same

3. But if the signs are different you will have to turn the subtraction sign into and addition sign and turn the second integer into the same number, but with the opposite sign

4. For example -2 - 0.5 equals -2.5

multiplying integers

1. for this one the sign you use at the end of the problem varies on the amount of negatives and positives in the math sentence so if there were two negative the answer would be positive if the two integers were positive it would still be positive but if one is positive and the other one is negative the answer is going to be negative

2. Even if the signs are different you would still multiply regular .

3. For example [-7]2 equals -14

Dividing integers

1. The rules about the negatives and positives are the same for dividing as they at effort multiplying.

2. Regardless of which sign is positive and negative you just divide normally

3. For example 2 / 0.5 equals 4
