1. Addition Multiplication Subtraction Division

2. 1.If the signs are the same, add the numbers and keep the same sign. 5 + 2 = 7- 8 + - 5 = - 12 2.If the signs are different, subtract the numbers. If you have more +’s the answer is +, and if you have more –’s the answer is -. - 12 + 3 = - 924 + - 12 = 12 Addition Rules HOME

3. 1.If the signs are the same, multiply and your answer will be positive. If the signs are different, multiply and your answer will be negative. - 6 * (-2) = 126 * 8 = 48 - 4 * 5 = - 205 * (-2) = - 10 Multiplication Rules HOME

4. 1.Change the sign of the second number and change the subtraction sign to an addition sign. Then follow the addition rules. 10 – 4 = ? = 10 + (-4) = 6 - 8 – (2) = ? = - 8 + (-2) = - 6 Subtraction Rules HOME

5. 1.If the signs are the same divide and your answer will be positive. If the signs are different, divide and your answer will be a negative. - 5 / (-15) = 36 / 18 = 3 - 20 / 4 = - 580 / (-10) = - 8 Division Rules HOME
