$$68 \times 15$$

Evaluate

$$1020$$

Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times99}68\\\underline{\times\phantom{99}15}\\\end{array}$$

Now multiply the first number with the 1^{st} digit in 2^{nd} number to get intermediate results. That is Multiply 68 with 5. Write the result 340 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}68\\\underline{\times\phantom{99}15}\\\phantom{\times9}340\\\end{array}$$

Now multiply the first number with the 2^{nd} digit in 2^{nd} number to get intermediate results. That is Multiply 68 with 1. Write the result 68 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}68\\\underline{\times\phantom{99}15}\\\phantom{\times9}340\\\underline{\phantom{\times9}68\phantom{9}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times99}68\\\underline{\times\phantom{99}15}\\\phantom{\times9}340\\\underline{\phantom{\times9}68\phantom{9}}\\\phantom{\times}1020\end{array}$$
