Math

In math we have been learning about how to multiply by powers of 10. When multiplying a whole number by a power of ten, just count how many zero you have and attached that to the whole number. Example: 56 × 10 There is only one zero, so 56 × 10 = 560 When multiplying a decimal by a power of ten , move the decimal point one place to the right for each zero you see after the 1 Example:0.56 × 100 There are 2 zeros, so move the decimal point two places to the right 0.56 x 100 = 56
