$$420 \cdot 69$$

Evaluate

$$28980$$

Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times99}420\\\underline{\times\phantom{999}69}\\\end{array}$$

Now multiply the first number with the 1^{st} digit in 2^{nd} number to get intermediate results. That is Multiply 420 with 9. Write the result 3780 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}420\\\underline{\times\phantom{999}69}\\\phantom{\times9}3780\\\end{array}$$

Now multiply the first number with the 2^{nd} digit in 2^{nd} number to get intermediate results. That is Multiply 420 with 6. Write the result 2520 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}420\\\underline{\times\phantom{999}69}\\\phantom{\times9}3780\\\underline{\phantom{\times}2520\phantom{9}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times99}420\\\underline{\times\phantom{999}69}\\\phantom{\times9}3780\\\underline{\phantom{\times}2520\phantom{9}}\\\phantom{\times}28980\end{array}$$
