Solve 40*52

$$40 \times 52$$

Evaluate

$$2080$$

Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times99}40\\\underline{\times\phantom{99}52}\\\end{array}$$

Now multiply the first number with the 1^{st} digit in 2^{nd} number to get intermediate results. That is Multiply 40 with 2. Write the result 80 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}40\\\underline{\times\phantom{99}52}\\\phantom{\times99}80\\\end{array}$$

Now multiply the first number with the 2^{nd} digit in 2^{nd} number to get intermediate results. That is Multiply 40 with 5. Write the result 200 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}40\\\underline{\times\phantom{99}52}\\\phantom{\times99}80\\\underline{\phantom{\times}200\phantom{9}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times99}40\\\underline{\times\phantom{99}52}\\\phantom{\times99}80\\\underline{\phantom{\times}200\phantom{9}}\\\phantom{\times}2080\end{array}$$
