Subtracting Integers Algebraically

How to Subtract Integers Algebraically 1.Rewrite the problem  Keep the first number the same  Change the problem from subtraction to addition  Make the last number its opposite 2.Now follow adding integer rules  Same sign – add the numbers keep the sign  Different signs – subtract the numbers, keep the sign of the greater absolute value

Examples – – Rewrite the problem Add the numbers and keep the sign Rewrite the problem Subtract the numbers and keep the sign of the greater absolute value

Practice Problems – – – Rewrite the problem. Then follow addition rules for integers. = -18 = -10 = 22 = -13 = -4 = 9 = -25
