Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times9}420\\\underline{\times\phantom{99}10}\\\end{array}$$

Now multiply the first number with the 1^{st} digit in 2^{nd} number to get intermediate results. That is Multiply 420 with 0. Write the result 0 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times9}420\\\underline{\times\phantom{99}10}\\\phantom{\times9999}0\\\end{array}$$

Now multiply the first number with the 2^{nd} digit in 2^{nd} number to get intermediate results. That is Multiply 420 with 1. Write the result 420 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times9}420\\\underline{\times\phantom{99}10}\\\phantom{\times9999}0\\\underline{\phantom{\times}420\phantom{9}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times9}420\\\underline{\times\phantom{99}10}\\\phantom{\times9999}0\\\underline{\phantom{\times}420\phantom{9}}\\\phantom{\times}4200\end{array}$$
