Question

Write an expression for the calculation “the product of 4 and 4 added to double the number 5”

Answer 1

4•4+2•5

4(4)+2(5)

4x4+2x5

4²+2(5)

Answer 2

The answer is:

`(4*4)+(2*5)`

Explanation:

In order to determine the answer, we have to know about the rules of the basic math operations.

In math, we have the basic operations:

• multiply
• add
• subtract
• divide

If we have all these basic operations in a expression, the order to solve every one is:

1. multiply/divide
2. add/subtract

Also, we need to know that if there is a phrase that says "the product of something", we have to multiply two values, in this case, 4 and 4.

Regarding to the phrase "added something" it means we have to add two expression, in this case, the product "4 and 4" and the next value "double 5".

Finally, the expression is:

`(4*4)+(2*5)`
