Solve 1545x241

$$1545x241$$

Evaluate

$$1545x_{241}$$

Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times99}1545\\\underline{\times\phantom{999}241}\\\end{array}$$

Now multiply the first number with the 1^{st} digit in 2^{nd} number to get intermediate results. That is Multiply 1545 with 1. Write the result 1545 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}1545\\\underline{\times\phantom{999}241}\\\phantom{\times99}1545\\\end{array}$$

Now multiply the first number with the 2^{nd} digit in 2^{nd} number to get intermediate results. That is Multiply 1545 with 4. Write the result 6180 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}1545\\\underline{\times\phantom{999}241}\\\phantom{\times99}1545\\\phantom{\times9}6180\phantom{9}\\\end{array}$$

Now multiply the first number with the 3^{rd} digit in 2^{nd} number to get intermediate results. That is Multiply 1545 with 2. Write the result 3090 at the end leaving 2 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}1545\\\underline{\times\phantom{999}241}\\\phantom{\times99}1545\\\phantom{\times9}6180\phantom{9}\\\underline{\phantom{\times}3090\phantom{99}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times99}1545\\\underline{\times\phantom{999}241}\\\phantom{\times99}1545\\\phantom{\times9}6180\phantom{9}\\\underline{\phantom{\times}3090\phantom{99}}\\\phantom{\times}372345\end{array}$$
