• help me i cant add or subtract intigers
• ex.1 same signs 2+(8)=10 normal math different sign 2+-9=7 subtraction
• okay
• if the signs are the same add like normal but if the negative number is bigger than the positive its negative it also goes the other way around.
• the rule of adding integers is if the signs are different subtracted
• additive inverse example 1: 2-(-9) change the sign to a + and also change the -9 to a positive 9 because of additive inverse.
• lets move on to subtractions
