$$20 \times 315$$

Evaluate

$$6300$$

Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times99}20\\\underline{\times\phantom{9}315}\\\end{array}$$

Now multiply the first number with the 1^{st} digit in 2^{nd} number to get intermediate results. That is Multiply 20 with 5. Write the result 100 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}20\\\underline{\times\phantom{9}315}\\\phantom{\times9}100\\\end{array}$$

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

$$\begin{array}{c}\phantom{\times99}20\\\underline{\times\phantom{9}315}\\\phantom{\times9}100\\\phantom{\times9}20\phantom{9}\\\end{array}$$

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.

$$\begin{array}{c}\phantom{\times99}20\\\underline{\times\phantom{9}315}\\\phantom{\times9}100\\\phantom{\times9}20\phantom{9}\\\underline{\phantom{\times}60\phantom{99}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times99}20\\\underline{\times\phantom{9}315}\\\phantom{\times9}100\\\phantom{\times9}20\phantom{9}\\\underline{\phantom{\times}60\phantom{99}}\\\phantom{\times}6300\end{array}$$
