4. Things to know: Adding Integers If signs are the same: We’re friends!! Add the values of the #’s & keep their sign. 6+5=11 -7+-3=-10 Subtracting Integers If signs are different : We’re at WAR The LARGER-valued number will win the sign battle. Subtract the values of the numbers to see by how much. 5+-7=-2 -3+8=5

5. Subtracting Integers Subtraction is the same as adding the opposite, so rewrite subtraction problems as addition problems and then use addition rules. -6-3= -6+-3= -9 4 - -9= 4+9= 13

6. Multiplying and Dividing Integers Same signs: POSITIVE answer Different sign: NEGATIVE answer 6 x 5= -4 x -3= -9 x 2= 8 x -7=
