$$20 \times 396$$

Evaluate

$$7920$$

Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times99}20\\\underline{\times\phantom{9}396}\\\end{array}$$

Now multiply the first number with the 1^{st} digit in 2^{nd} number to get intermediate results. That is Multiply 20 with 6. Write the result 120 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}20\\\underline{\times\phantom{9}396}\\\phantom{\times9}120\\\end{array}$$

Now multiply the first number with the 2^{nd} digit in 2^{nd} number to get intermediate results. That is Multiply 20 with 9. Write the result 180 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}20\\\underline{\times\phantom{9}396}\\\phantom{\times9}120\\\phantom{\times}180\phantom{9}\\\end{array}$$

Now multiply the first number with the 3^{rd} digit in 2^{nd} number to get intermediate results. That is Multiply 20 with 3. Write the result 60 at the end leaving 2 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}20\\\underline{\times\phantom{9}396}\\\phantom{\times9}120\\\phantom{\times}180\phantom{9}\\\underline{\phantom{\times}60\phantom{99}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times99}20\\\underline{\times\phantom{9}396}\\\phantom{\times9}120\\\phantom{\times}180\phantom{9}\\\underline{\phantom{\times}60\phantom{99}}\\\phantom{\times}7920\end{array}$$
