Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times99}345\\\underline{\times\phantom{99}123}\\\end{array}$$

Now multiply the first number with the 1^{st} digit in 2^{nd} number to get intermediate results. That is Multiply 345 with 3. Write the result 1035 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}345\\\underline{\times\phantom{99}123}\\\phantom{\times9}1035\\\end{array}$$

Now multiply the first number with the 2^{nd} digit in 2^{nd} number to get intermediate results. That is Multiply 345 with 2. Write the result 690 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}345\\\underline{\times\phantom{99}123}\\\phantom{\times9}1035\\\phantom{\times9}690\phantom{9}\\\end{array}$$

Now multiply the first number with the 3^{rd} digit in 2^{nd} number to get intermediate results. That is Multiply 345 with 1. Write the result 345 at the end leaving 2 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}345\\\underline{\times\phantom{99}123}\\\phantom{\times9}1035\\\phantom{\times9}690\phantom{9}\\\underline{\phantom{\times}345\phantom{99}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times99}345\\\underline{\times\phantom{99}123}\\\phantom{\times9}1035\\\phantom{\times9}690\phantom{9}\\\underline{\phantom{\times}345\phantom{99}}\\\phantom{\times}42435\end{array}$$
