# Multiplying: Equal Rows

Math story 101 · Multiplication · Grade 3 · 0:32

## Read the story

Here are 4 rows. In each row there are 5 dots.

We count: 5 plus 5 plus 5 plus 5 is 20.

Multiplying is shorter: 4 times 5 is 20.

**What is 3 times 7?**

## Answer and working

Correct! 7 plus 7 plus 7 is 21. So 3 times 7 is 21.

`3 × 7 = 21`
