$$42 \times 715$$

Evaluate

$$30030$$

Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times999}42\\\underline{\times\phantom{99}715}\\\end{array}$$

Now multiply the first number with the 1^{st} digit in 2^{nd} number to get intermediate results. That is Multiply 42 with 5. Write the result 210 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times999}42\\\underline{\times\phantom{99}715}\\\phantom{\times99}210\\\end{array}$$

Now multiply the first number with the 2^{nd} digit in 2^{nd} number to get intermediate results. That is Multiply 42 with 1. Write the result 42 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times999}42\\\underline{\times\phantom{99}715}\\\phantom{\times99}210\\\phantom{\times99}42\phantom{9}\\\end{array}$$

Now multiply the first number with the 3^{rd} digit in 2^{nd} number to get intermediate results. That is Multiply 42 with 7. Write the result 294 at the end leaving 2 spaces to the right like this.

$$\begin{array}{c}\phantom{\times999}42\\\underline{\times\phantom{99}715}\\\phantom{\times99}210\\\phantom{\times99}42\phantom{9}\\\underline{\phantom{\times}294\phantom{99}}\\\end{array}$$

Now add the intermediate results to get final answer.

$$\begin{array}{c}\phantom{\times999}42\\\underline{\times\phantom{99}715}\\\phantom{\times99}210\\\phantom{\times99}42\phantom{9}\\\underline{\phantom{\times}294\phantom{99}}\\\phantom{\times}30030\end{array}$$
