Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times99}1280\\\underline{\times\phantom{999}340}\\\end{array}$$

Now multiply the first number with the 1^{st} digit in 2^{nd} number to get intermediate results. That is Multiply 1280 with 0. Write the result 0 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}1280\\\underline{\times\phantom{999}340}\\\phantom{\times999999}0\\\end{array}$$

Now multiply the first number with the 2^{nd} digit in 2^{nd} number to get intermediate results. That is Multiply 1280 with 4. Write the result 5120 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}1280\\\underline{\times\phantom{999}340}\\\phantom{\times999999}0\\\phantom{\times9}5120\phantom{9}\\\end{array}$$

Now multiply the first number with the 3^{rd} digit in 2^{nd} number to get intermediate results. That is Multiply 1280 with 3. Write the result 3840 at the end leaving 2 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}1280\\\underline{\times\phantom{999}340}\\\phantom{\times999999}0\\\phantom{\times9}5120\phantom{9}\\\underline{\phantom{\times}3840\phantom{99}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times99}1280\\\underline{\times\phantom{999}340}\\\phantom{\times999999}0\\\phantom{\times9}5120\phantom{9}\\\underline{\phantom{\times}3840\phantom{99}}\\\phantom{\times}435200\end{array}$$
