1. 1.2 ADDING AND SUBTRACTING INTEGERS I can find the sums and differences of integers by using a number line or using SSA/DSS.

2. YOU CAN ADD OR SUBTRACT USING A NUMBER LINE 3+5

3. YOU CAN ADD OR SUBTRACT USING A NUMBER LINE 3+(-5)

4. YOU CAN ADD OR SUBTRACT USING A NUMBER LINE -3+5

5. YOU CAN ADD OR SUBTRACT USING A NUMBER LINE -3+(-5)

6. ABSOLUTE VALUE The distance between a number and 0 on the number line.

7. SAME SIGNS ADD (SSA) To add two numbers with the same sign, add their absolute value. The sum has the same sign as the addends. Examples: 3+4 -3 + (-4)

8. DIFFERENT SIGNS SUBTRACT (DSS) To add two numbers with different signs, subtract the absolute values. The sum has the same sign as the addend with the greater absolute value. Examples: -3 + 4 3 + (-4)

9. INVERSE PROPERTY OF ADDITION Two number the same distance from 0 on a number line are called opposites (ex: 3 and -3) A number and its opposite are called additive inverses The inverse property of addition says: For every real number a, there is an additive inverse –a such that a + (-a) = 0 Examples?

10. SUBTRACTING INTEGERS To subtract a real number, add the opposite a – b = a + (-b) 3 – 5 3 – (-5)
