## Learn Â to multiply numbers Â from Certified Online Pre-Algebra Tutor

Terms which describe the numbers in a multiplication problem.

**Factors or Multipliers** are the numbers that are being multiplied together.

Product is the result of multiplying the multiplicand by the multiplier.

### Rule for multiplying numbers ending in zeroes:

**First multiply the numbers without considering the zeroes, then count the number of zeroes in both the numbers and place these zeroes to the right place of the result.**

### Letâ€™s understand with an example

Last year, 40 people each paid $800 for an insurance package. How much did the people pay in total?

There were 40 people, each of whom paid $800. Multiply 40 by $800.

First, multiply 4 and $8.

**4 Ã— $8 = $32**

Now count the zeroes in both numbers.

**40 Ã— $800 = ?**

There are 3 zeroes in all. Write 3 zeroes after 32.

**40 Ã— $800 = $32,000**

The people spent $32,000 in all.
