Question

$$11011 \times 101$$

Evaluate

$1112111$

Steps For Long Multiplication

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

$$\begin{array}{c}\phantom{\times99}11011\\\underline{\times\phantom{9999}101}\\\end{array}$$

Now multiply the first number with the $1^{st}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 11011 with 1. Write the result 11011 at the end leaving 0 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}11011\\\underline{\times\phantom{9999}101}\\\phantom{\times99}11011\\\end{array}$$

Now multiply the first number with the $2^{nd}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 11011 with 0. Write the result 0 at the end leaving 1 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}11011\\\underline{\times\phantom{9999}101}\\\phantom{\times99}11011\\\phantom{\times999999}0\phantom{9}\\\end{array}$$

Now multiply the first number with the $3^{rd}$ digit in $2^{nd}$ number to get intermediate results. That is Multiply 11011 with 1. Write the result 11011 at the end leaving 2 spaces to the right like this.

$$\begin{array}{c}\phantom{\times99}11011\\\underline{\times\phantom{9999}101}\\\phantom{\times99}11011\\\phantom{\times999999}0\phantom{9}\\\underline{\phantom{\times}11011\phantom{99}}\\\end{array}$$

Now add the intermediate results to get final answer.
