$$1000 \times 800$$

Evaluate

$$800000$$

Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times99}1000\\\underline{\times\phantom{999}800}\\\end{array}$$

Now multiply the first number with the 1^{st} digit in 2^{nd} number to get intermediate results. That is Multiply 1000 with 0. Write the result 0 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}1000\\\underline{\times\phantom{999}800}\\\phantom{\times999999}0\\\end{array}$$

Now multiply the first number with the 2^{nd} digit in 2^{nd} number to get intermediate results. That is Multiply 1000 with 0. Write the result 0 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}1000\\\underline{\times\phantom{999}800}\\\phantom{\times999999}0\\\phantom{\times99999}0\phantom{9}\\\end{array}$$

Now multiply the first number with the 3^{rd} digit in 2^{nd} number to get intermediate results. That is Multiply 1000 with 8. Write the result 8000 at the end leaving 2 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}1000\\\underline{\times\phantom{999}800}\\\phantom{\times999999}0\\\phantom{\times99999}0\phantom{9}\\\underline{\phantom{\times}8000\phantom{99}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times99}1000\\\underline{\times\phantom{999}800}\\\phantom{\times999999}0\\\phantom{\times99999}0\phantom{9}\\\underline{\phantom{\times}8000\phantom{99}}\\\phantom{\times}800000\end{array}$$

Factor

$$2^{8}\times 5^{5}$$
