Expanded form of 920,831

$\Rightarrow$  The number which is multiple of $2$ is called an even number.

$999 = 100 \times 9 + 9\times10+9$

$99 = 10 \times 9 + 9$

$72 = 10 \times 7 + 2$

$11 = 10 \times 1 + 1$

The general form of any three digit number is, $abc = a \times 100 + b \times 10 + c$
So, $753 = 7 \times 100 + 5 \times 10 + 3$

The usual form: $6 \times 10 +9 = 60+9 = 69$

The general form of any two digit number is, $ab = a \times 10 + b$
So, $9 \times 10 + 0$ is in general form.
