Remember the rules for multiplying signed numbers and you will always be able to keep the signs straight:


	positive x positive = positive
	positive x negative = negative
	negative x positive = negative
	negative x negative = positive

Here are a few more examples:


	-3 x 10 = -30			-3 x -10 = 30

	3 x -10 = -30			 3 x 10  = 30
