You can put this solution on YOUR website! ADD +&+=+, -&-=-, +&- OR -&+ THE ANSWER HAS THE SIGN OF THE LARGEST NUMBER.
EXAMPLE +3+3=+6 , -3-3=-6, +8-16=-8, -8+16=+8
---------------------------------------------------------------------
SUBTRACT ALWAYS TAKE THE DIFFERENCE & USE THE SIGN OF THE LARGER NUMBER.
EXAMPLE +5-9=-4, -13+7=-6
---------------------------------------------------------------------
MULTIPLICATION +*+=+, -*-=+, +*-=-, -*+=-
EXAMPLE +4*+4=+16, -5*-6=+30, -3*+2=-6, +7*-2=-14
-----------------------------------------------------------------------
DIVISION +/+=+, -/-=+, +/-=-, -/+=-
EXAMPLE +9/+3=+3, -12/-6=+2, +24/-6=-4, -30/+5=-6
