Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times999}155\\\underline{\times\phantom{999}820}\\\end{array}$$

Now multiply the first number with the 1^{st} digit in 2^{nd} number to get intermediate results. That is Multiply 155 with 0. Write the result 0 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times999}155\\\underline{\times\phantom{999}820}\\\phantom{\times999999}0\\\end{array}$$

Now multiply the first number with the 2^{nd} digit in 2^{nd} number to get intermediate results. That is Multiply 155 with 2. Write the result 310 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times999}155\\\underline{\times\phantom{999}820}\\\phantom{\times999999}0\\\phantom{\times99}310\phantom{9}\\\end{array}$$

Now multiply the first number with the 3^{rd} digit in 2^{nd} number to get intermediate results. That is Multiply 155 with 8. Write the result 1240 at the end leaving 2 spaces to the right like this.

$$\begin{array}{c}\phantom{\times999}155\\\underline{\times\phantom{999}820}\\\phantom{\times999999}0\\\phantom{\times99}310\phantom{9}\\\underline{\phantom{\times}1240\phantom{99}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times999}155\\\underline{\times\phantom{999}820}\\\phantom{\times999999}0\\\phantom{\times99}310\phantom{9}\\\underline{\phantom{\times}1240\phantom{99}}\\\phantom{\times}127100\end{array}$$
