Exercise 59 Page 79

According to the order of operations, expressions inside parentheses are evaluated first, followed by exponents, then multiplication and division, and finally addition and subtraction are evaluated last. We can use the acronym PEMDAS to help us remember the correct order!

For the given expression, this means evaluating the product first.

1.047* 5 -0.88 To find the product, we 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.

We found that the product is 5.235. 2.4* 16 -0.88= 5.235-0.88=4.355 The expression is equal to 4.355.
