Multiply by Repeated Addition
We can multiply by repeated addition!
Drag the items to create equal groups and watch how the numbers add up:
images/add-repeat.js
Example: we can think of 3 × 4 as:
3 groups of items...
...with 4 items in each group.
And these all give the same answer:
- 4 + 4 + 4 = 12
- 3 × 4 = 12
- 4 × 3 = 12
Note that 4 × 3 means 4 groups of 3:
3 + 3 + 3 + 3 = 12
We get the same total either way!
This is the basic idea behind multiplication of whole numbers.
