Repeated adding to times
You learn to turn an addition of the same number into a multiplication and work it out.
How to work it out
- If you keep adding the same number, you make a multiplication.
- Count how many times the number appears: that is the first number of the multiplication.
4 × 5
5 + 5 + 5 + 5
- Look at which number keeps appearing: that is 5.
- Count how many times the number appears: that is 4 times.
- Write the multiplication and work it out: 4 × 5 = 20.
