Solve {r}{100}{*198}

$$\left. \begin{array} { r } { 100 } \\ { \times 198 } \end{array} \right.$$

Evaluate

$$19800$$

Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times99}100\\\underline{\times\phantom{99}198}\\\end{array}$$

Now multiply the first number with the 1^{st} digit in 2^{nd} number to get intermediate results. That is Multiply 100 with 8. Write the result 800 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}100\\\underline{\times\phantom{99}198}\\\phantom{\times99}800\\\end{array}$$

Now multiply the first number with the 2^{nd} digit in 2^{nd} number to get intermediate results. That is Multiply 100 with 9. Write the result 900 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}100\\\underline{\times\phantom{99}198}\\\phantom{\times99}800\\\phantom{\times9}900\phantom{9}\\\end{array}$$

Now multiply the first number with the 3^{rd} digit in 2^{nd} number to get intermediate results. That is Multiply 100 with 1. Write the result 100 at the end leaving 2 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}100\\\underline{\times\phantom{99}198}\\\phantom{\times99}800\\\phantom{\times9}900\phantom{9}\\\underline{\phantom{\times}100\phantom{99}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times99}100\\\underline{\times\phantom{99}198}\\\phantom{\times99}800\\\phantom{\times9}900\phantom{9}\\\underline{\phantom{\times}100\phantom{99}}\\\phantom{\times}19800\end{array}$$

Factor

$$2^{3}\times 3^{2}\times 5^{2}\times 11$$
