Question

$$56 \times 45$$

Evaluate

$2520$

Steps For Long Multiplication

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

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

Now multiply the first number with the $1^{st}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 56 with 5. Write the result 280 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}56\\\underline{\times\phantom{99}45}\\\phantom{\times9}280\\\end{array}$$

Now multiply the first number with the $2^{nd}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 56 with 4. Write the result 224 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}56\\\underline{\times\phantom{99}45}\\\phantom{\times9}280\\\underline{\phantom{\times}224\phantom{9}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times99}56\\\underline{\times\phantom{99}45}\\\phantom{\times9}280\\\underline{\phantom{\times}224\phantom{9}}\\\phantom{\times}2520\end{array}$$
