$$45 * 56$$

Evaluate

$$2520$$

Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times99}45\\\underline{\times\phantom{99}56}\\\end{array}$$

Now multiply the first number with the 1^{st} digit in 2^{nd} number to get intermediate results. That is Multiply 45 with 6. Write the result 270 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}45\\\underline{\times\phantom{99}56}\\\phantom{\times9}270\\\end{array}$$

Now multiply the first number with the 2^{nd} digit in 2^{nd} number to get intermediate results. That is Multiply 45 with 5. Write the result 225 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}45\\\underline{\times\phantom{99}56}\\\phantom{\times9}270\\\underline{\phantom{\times}225\phantom{9}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times99}45\\\underline{\times\phantom{99}56}\\\phantom{\times9}270\\\underline{\phantom{\times}225\phantom{9}}\\\phantom{\times}2520\end{array}$$
