-8 + -4 =

• DIFFERENT SIGNS so I SUBTRACT and use sign of greater ABSOLUTE VALUE

• SAME SIGNS so I ADD and KEEP the SAME SIGN

-8 + -4 =

• -4

• 4

• -12

• 12

-6 + 11 =

• DIFFERENT SIGNS

• SAME SIGNS

-6 + 11 =

• SUBTRACT and use sign of greater ABSOLUTE VALUE

• ADD and use SAME SIGN

-6 + 11 =

• 5

• -5

• -17

• 17

8 + (-2) =

• SUBTRACT and use sign of greater ABSOLUTE VALUE

• ADD and use SAME SIGN

8 + -2 =
