Remember - To multiply by $10$, move the decimal point one space to the right (as there is $1$ zero in $10$)

\n

To multiply by $100$, move the decimal point two spaces to the right (as there is $2$ zeroes in $100$)

\n

To multiply by $1000$, move the decimal point three spaces to the right (as there is $3$ zeroes in $1000$)

\n

\n

If you are multiplying by a decimal, the number of zeroes tells you how many spaces to move the decimal places to the left:

\n

$0.1$ = $1$ zero, $1$ space to the left;

\n

$0.01$ = $2$ zeroes = $2$ spaces to the left;

\n

$0.001$ = $3$ spaces to the left.

\n

\n

This is useful to know as:

\n

Multiplying by $0.1$ = Dividing by $10$

\n

Multiplying by $0.01$ = Dividing by $100$

\n

Multiplying by $0.001$ = Dividing by $1000$
