$$\left. \begin{array} { r } { 30 } \\ { \times 15 } \end{array} \right.$$

Evaluate

$$450$$

Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times9}30\\\underline{\times\phantom{9}15}\\\end{array}$$

Now multiply the first number with the 1^{st} digit in 2^{nd} number to get intermediate results. That is Multiply 30 with 5. Write the result 150 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times9}30\\\underline{\times\phantom{9}15}\\\phantom{\times}150\\\end{array}$$

Now multiply the first number with the 2^{nd} digit in 2^{nd} number to get intermediate results. That is Multiply 30 with 1. Write the result 30 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times9}30\\\underline{\times\phantom{9}15}\\\phantom{\times}150\\\underline{\phantom{\times}30\phantom{9}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times9}30\\\underline{\times\phantom{9}15}\\\phantom{\times}150\\\underline{\phantom{\times}30\phantom{9}}\\\phantom{\times}450\end{array}$$

Factor

$$2\times 3^{2}\times 5^{2}$$
