Question

$$420 \times 13$$

Evaluate

$5460$

Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times9}420\\\underline{\times\phantom{99}13}\\\end{array}$$

Now multiply the first number with the $1^{st}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 420 with 3. Write the result 1260 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times9}420\\\underline{\times\phantom{99}13}\\\phantom{\times}1260\\\end{array}$$

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.

$$\begin{array}{c}\phantom{\times9}420\\\underline{\times\phantom{99}13}\\\phantom{\times}1260\\\underline{\phantom{\times}420\phantom{9}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times9}420\\\underline{\times\phantom{99}13}\\\phantom{\times}1260\\\underline{\phantom{\times}420\phantom{9}}\\\phantom{\times}5460\end{array}$$
