Created: To provide answers to subtraction problems:{4-6=-2}Addition: -both positive~add,sum is positve{3+8=11}

-both negative~add,sum is negative{-3+-8=-11

-signs different~more(how much?)+or more-{3+-5=-2}Subtraction: -add the opposite

{8- -4=8+ +4=12}Multiplication

& Division: -if signs are the same.....answer is positive

{3x4=12} {-3x-4=12}

{12/3=4} {12/3=4}

-if signs are different.....answer is negative

{-3x4=-12} {+3x-4=-12}

{12/-3=-4} {-12/3=4}
