Steps For Long Multiplication

First line up the numbers vertically and match the places from the right like this.

$$\begin{array}{c}\phantom{\times9}18\\\underline{\times\phantom{9}18}\\\end{array}$$

Now multiply the first number with the $1^{st}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 18 with 8. Write the result 144 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times9}18\\\underline{\times\phantom{9}18}\\\phantom{\times}144\\\end{array}$$

Now multiply the first number with the $2^{nd}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 18 with 1. Write the result 18 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times9}18\\\underline{\times\phantom{9}18}\\\phantom{\times}144\\\underline{\phantom{\times}18\phantom{9}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times9}18\\\underline{\times\phantom{9}18}\\\phantom{\times}144\\\underline{\phantom{\times}18\phantom{9}}\\\phantom{\times}324\end{array}$$
