| A | B |
|---|
| Adding Integers with like signs | Add the integers; the answer has the same sign |
| Adding Integer with different signs | Take the absolute value of the terms; subtract the smaller term from the larger; the answer has the sign of the term with the largest absolute value |
| Subtracting Integers | Add the opposite of the second term then follow the rules for addition |
| Multiplying Integers with an odd number of negative factors | The answer will be negative; Multiply the factors |
| Multiplying Integers with an even number of negative factors | The answer will positive; Multiply the factors |
| Dividing Integers with like sign | The answer will be positive; divide the integers |
| Dividing Integers with different sign | The answer will be negative; divide the integers |
| Any number divide by 0 ( 3/0) = | Undefined |
| 0 divide by any number (0 / 3) = | 0 |
| 1 times any number = | that number |
| -4 + -2 = | -6 |
| -4 + 2 = | -2 |
| -4 * -2 = | + 8 |
| -8 / -2= | + 4 |
| -3 - ( -5)= | +2 |
| Any number times 0 ( 5 * 0) | 0 |
