Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times999}999\\\underline{\times\phantom{999}123}\\\end{array}$$

Now multiply the first number with the 1^{st} digit in 2^{nd} number to get intermediate results. That is Multiply 999 with 3. Write the result 2997 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times999}999\\\underline{\times\phantom{999}123}\\\phantom{\times99}2997\\\end{array}$$

Now multiply the first number with the 2^{nd} digit in 2^{nd} number to get intermediate results. That is Multiply 999 with 2. Write the result 1998 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times999}999\\\underline{\times\phantom{999}123}\\\phantom{\times99}2997\\\phantom{\times9}1998\phantom{9}\\\end{array}$$

Now multiply the first number with the 3^{rd} digit in 2^{nd} number to get intermediate results. That is Multiply 999 with 1. Write the result 999 at the end leaving 2 spaces to the right like this.

$$\begin{array}{c}\phantom{\times999}999\\\underline{\times\phantom{999}123}\\\phantom{\times99}2997\\\phantom{\times9}1998\phantom{9}\\\underline{\phantom{\times9}999\phantom{99}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times999}999\\\underline{\times\phantom{999}123}\\\phantom{\times99}2997\\\phantom{\times9}1998\phantom{9}\\\underline{\phantom{\times9}999\phantom{99}}\\\phantom{\times}122877\end{array}$$
