Addition Multiplication Subtraction Division

1.If the signs are the same, add the numbers and keep the same sign = = 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 Addition Rules HOME

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 = * 5 = * (-2) = - 10 Multiplication Rules HOME

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) = – (2) = ? = (-2) = - 6 Subtraction Rules HOME

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 = / 4 = / (-10) = - 8 Division Rules HOME
