Multiplying by 10
When we multiply by 10 we are making the number ten times bigger.

2. In the decimal system, each column has numbers 10 x bigger than the next one
1000
100 10 1

3. If we multiply 6 by ten it will move into the next column
We must put a 0 in the empty units column to hold the place – 6 x 10 = 60

4. Don’t forget to add the zero in the empty column!
Let’s try with some other numbers Th h t u 2 3 20
200 3 30
Don’t forget to add the zero in the empty column!
23 x 10 = 230

5. Let’s try these together!
48 x 10 =
93 x 10 =
134 x 10 =
256 x 10 =
889 x 10 =
480
930
1340
2560
8890
