Solve 15*16=

$$15 \times 16=$$

Evaluate

$$240$$

Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times9}15\\\underline{\times\phantom{9}16}\\\end{array}$$

Now multiply the first number with the 1^{st} digit in 2^{nd} number to get intermediate results. That is Multiply 15 with 6. Write the result 90 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times9}15\\\underline{\times\phantom{9}16}\\\phantom{\times9}90\\\end{array}$$

Now multiply the first number with the 2^{nd} digit in 2^{nd} number to get intermediate results. That is Multiply 15 with 1. Write the result 15 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times9}15\\\underline{\times\phantom{9}16}\\\phantom{\times9}90\\\underline{\phantom{\times}15\phantom{9}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times9}15\\\underline{\times\phantom{9}16}\\\phantom{\times9}90\\\underline{\phantom{\times}15\phantom{9}}\\\phantom{\times}240\end{array}$$
