Answer by terbear1963(43)   (Show Source):
You can put this solution on YOUR website! THE RULES FOR SIGNED NUMBERS ARE EASY!!! JUST REMEMBER THESE RULES : (1) IF THE SIGNS ARE ALIKE, ADD AND KEEP THE SIGN. EX : -4 + -3 = -7 AND (+3) + (+4)= (+7) //// (2) IF THE SIGNS ARE UNLIKE, SUBTRACT AND TAKE THE SIGN OF THE LARGER NUMBER. EX : (-15)+(+4)= -11 AND (-20)+(+35)=(+15) YOU DON'T ALWAYS HAVE TO USE THE ( ) AND THE + SIGN, BUT, IT MAKES IT CLEARER WHEN USING POSITIVE AND NEGATIVE NUMBERS!!! I HOPE THIS HELPS?!
