Math Help—How to Work out the Product and Sum of Two Numbers

Updated on March 18, 2017

If you are asked to work out the product of two numbers then you need to multiply the two numbers together. If you are asked to find the sum of two numbers then you need to add the numbers together.

Example 1

Work out the product and sum of 6 and 8.

The product of 6 and 8 is 6 × 8 = 48

The sum of 6 and 8 is 6 + 8 = 14

Example 2

Work out the product and sum of 9 and 3.

The product of 9 and 3 is 9 × 3 = 27

The sum of 9 and 3 is 9 + 3 = 12

Example 3

Work out the product and sum of -7 and 9

The product of -7 and 9 is -7 × 9 = -63

The sum of -7 and 9 is -7 + 9 = 2

Example 4

Write down two numbers that have a product of 42.

All you need to do is look for two numbers that multiply to give 42.

There are several possible answers:

1 and 42 or 2 and 21 or 3 and 14 or 6 and 7.

You could even have:

-1 and -42 or -2 and -21 or -3 and -14 or -6 and -7.

Example 5

Work out the product of 2, 4 and 9.

The product means that you need to multiply the three numbers together.

2 × 4 × 9 = 72.

Example 6

Work out the sum of 2, 4 and 9.

This time you need to add the numbers together as you are finding the sum.

2 + 4 + 9 = 15.

So that’s all you need to know about product and sum:

Product means multiply.

Sum means add.

Questions & Answers

  • what is the sum and product of -5 and -12?

    Sum means you need to add the numbers (-5 + -12 = -5 - 12 = -17).

    Product means you need to multiply the numbers (-5 multiplied by -12 = 60).

  • Can you find two numbers which have a sum of 13 and a product of 12?

    Sum means add and product means multiply.

    The two numbers are 1 and 12, as 1 + 12 = 13 and 1 multiplied by 12 gives 12.

  • Two numbers have a sum of 5 and a product of 6 what are the numbers?

    The two numbers are 3 and 2.

    This is becuase 3 + 2 gives 5, and 3 multiplied by 2 gives 6.

  • Eight times the sum of 5 and some number is 184. What is the number?

    First divide 184 by 8 to give 23.

    Next subtract 5 from 23 to give 18.

    So the answer is 18.
