Objective
In this challenge, we will use loops to do some math. Check out the Tutorial tab to learn more.
Task
Given an integer, , print its first multiples. Each multiple (where ) should be printed on a new line in the form: n x i = result.
Example
The printout should look like this:
3 x 1 = 3
3 x 2 = 6
3 x 3 = 9
3 x 4 = 12
3 x 5 = 15
3 x 6 = 18
3 x 7 = 21
3 x 8 = 24
3 x 9 = 27
3 x 10 = 30
Input Format
A single integer, n.
Constraints
- 2 <= n <= 20
Output Format
Print 10 lines of output; each line i (where 1 <= i <= 10) contains the result of n x i in the form:
n x i = result.
Sample Input
2
Sample Output
2 x 1 = 2
2 x 2 = 4
2 x 3 = 6
2 x 4 = 8
2 x 5 = 10
2 x 6 = 12
2 x 7 = 14
2 x 8 = 16
2 x 9 = 18
2 x 10 = 20
