Integer Practice Problems - Addition
Addition Rules Summary –
ADDING TWO ALIKE SIGNS – two positive numbers or two negative numbers
1. Add absolute values
2. Attach same sign to the answer
Example:
Adding two positives integers
4 + 5 = 9
Adding two negative integers
(-4) + (-5) = (-9)
ADDING TWO UNLIKE SIGNS
- 6 + 4 = ?
1. Subtract absolute values
2. Use the sign of the number with the larger absolute value
| - 6| = 6 | 4 | = 4
Remember to put the larger number first when subtracting two numbers. -- > 6 - 4 = 2
Six is larger. So, the answer will have a negative sign.
- 6 + 4 = - 2
