Multiplication is ...

... (in its simplest form) repeated addition.
Here we see that 6+6+6 (three 6s)
make 18

It can also be said that 3+3+3+3+3+3 (six 3s) make 18
But we can also multiply by fractions or decimals, which goes beyond the simple idea of repeated addition:

Example: 3.5 × 5 = 17.5
which is 3.5 lots of 5, or 5 lots of 3.5

Division is ...

... splitting into equal parts or groups. It is the result of "fair sharing".
Division has its own special words to remember.
Let's take the simple question of dividing 22 by 5. The answer is 4, with 2 left over. Here we see the important words:
