Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times999}405\\\underline{\times\phantom{999}395}\\\end{array}$$

Now multiply the first number with the 1^{st} digit in 2^{nd} number to get intermediate results. That is Multiply 405 with 5. Write the result 2025 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times999}405\\\underline{\times\phantom{999}395}\\\phantom{\times99}2025\\\end{array}$$

Now multiply the first number with the 2^{nd} digit in 2^{nd} number to get intermediate results. That is Multiply 405 with 9. Write the result 3645 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times999}405\\\underline{\times\phantom{999}395}\\\phantom{\times99}2025\\\phantom{\times9}3645\phantom{9}\\\end{array}$$

Now multiply the first number with the 3^{rd} digit in 2^{nd} number to get intermediate results. That is Multiply 405 with 3. Write the result 1215 at the end leaving 2 spaces to the right like this.

$$\begin{array}{c}\phantom{\times999}405\\\underline{\times\phantom{999}395}\\\phantom{\times99}2025\\\phantom{\times9}3645\phantom{9}\\\underline{\phantom{\times}1215\phantom{99}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times999}405\\\underline{\times\phantom{999}395}\\\phantom{\times99}2025\\\phantom{\times9}3645\phantom{9}\\\underline{\phantom{\times}1215\phantom{99}}\\\phantom{\times}159975\end{array}$$
