Question

Multiplication and division are related operations.Look at these examples.-2.4 = -82-4 = 8(-2) (-4) = 88=(-4) = -22-(-4) = -8-8• (-4) = 2-8 4 = -28 -4 = 2Think about the signs of the factors and the sign of theproduct in the multiplication problems. How do the signsof the numbers you are dividing relate to their quotients?

Answer 1

When we are multiplying or dividing two numbers, the resulting sign depends on the sign of the two numbers:

If both numbers are positive, the product or quotient is a positive number.

If both numbers are negative, the product or quotient is a positive number.

If one number is positive and the other is negative, the product or quotient is a negative number.

We can see this happening in the eight examples given.
