# Solution Review: Multiplication Table of a Number

In this lesson, we'll look at the explanation of the last challenge.

## We'll cover the following

Let’s look at the solution first before jumping into the explanation:

$num = 11; # change values to print table of your choice$ans = ""; #returns the computed values in this string$i = 1;while($i <= 10){$answer = $num * $i;$ans .= $answer . " "; # .= operator append the result in $ans$i++;}print $ans;

## Explanation

We first initialized the `$num`

to our input value, whose table will be computed and printed. `while`

runs a total of ten times. In each iteration, the result of multiplication is concatenated with the previous value of the string `$ans`

(which has been initialized as an empty string) and a space. It prints the final answer `$ans`

after the loop completes its execution.
