#### Integer Practice Problems - Addition

ADDING TWO ALIKE SIGNS – two positive numbers or two negative numbers

2. Attach same sign to the answer

Example:
4 + 5 = 9

(-4) + (-5) = (-9)

- 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

Add two integers with different signs by ___________________ the __________ values.

Then, the sign of the answer is determined by the integer with the _______________ absolute value.
