Evaluate

$$3200$$

Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times99}40\\\underline{\times\phantom{99}80}\\\end{array}$$

Now multiply the first number with the 1^{st} digit in 2^{nd} number to get intermediate results. That is Multiply 40 with 0. Write the result 0 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}40\\\underline{\times\phantom{99}80}\\\phantom{\times9999}0\\\end{array}$$

Now multiply the first number with the 2^{nd} digit in 2^{nd} number to get intermediate results. That is Multiply 40 with 8. Write the result 320 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}40\\\underline{\times\phantom{99}80}\\\phantom{\times9999}0\\\underline{\phantom{\times}320\phantom{9}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times99}40\\\underline{\times\phantom{99}80}\\\phantom{\times9999}0\\\underline{\phantom{\times}320\phantom{9}}\\\phantom{\times}3200\end{array}$$
