Exercise 5 Page 84

When multiplying real numbers, the product will be positive if the signs are the same and it will be negative if the signs are different. cc Same Sign & Different Signs (+)(+)=(+) & (+)(-)=(-) (-)(-)=(+) & (-)(+)=(-) We want to evaluate the given expression. - 4.4 * (- 6.02) In our case both numbers are negative, so the product will be positive.

- 4.4(- 6.02)

- a(- b)=a* b

4.4(6.02)

To find the product, we can multiply just as we do with two whole numbers. At first, we ignore any decimal points.

Then we place the decimal point in the product by counting the number of decimal places in each factor.

The product of - 4.4 and - 6.02 is 26.488.
