Remember For Addition:Remember For Addition:
When the signs are the same, add When the signs are the same, add and keep the sign: and keep the sign: • 2+2= 42+2= 4• -2+(-2)= -4-2+(-2)= -4
When the signs are different, subtract When the signs are different, subtract and keep the sign of the larger and keep the sign of the larger number:number:• 6+(-2)=6+(-2)=• -6+2=-6+2=
