Solve 400*18

$$400 \times 18$$

Evaluate

$$7200$$

Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times9}400\\\underline{\times\phantom{99}18}\\\end{array}$$

Now multiply the first number with the 1^{st} digit in 2^{nd} number to get intermediate results. That is Multiply 400 with 8. Write the result 3200 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times9}400\\\underline{\times\phantom{99}18}\\\phantom{\times}3200\\\end{array}$$

Now multiply the first number with the 2^{nd} digit in 2^{nd} number to get intermediate results. That is Multiply 400 with 1. Write the result 400 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times9}400\\\underline{\times\phantom{99}18}\\\phantom{\times}3200\\\underline{\phantom{\times}400\phantom{9}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times9}400\\\underline{\times\phantom{99}18}\\\phantom{\times}3200\\\underline{\phantom{\times}400\phantom{9}}\\\phantom{\times}7200\end{array}$$

Factor

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