Java Loops I

Objective

In this challenge, we're going to use loops to help us do some simple math.

Task

Given an integer, N, print its first 10 multiples. Each multiple N * i (where 1 <= i <= 10) should be printed on a new line in the form: N x i = result.

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 * 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
Sample Output
2
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

//System.out.printf("%d x %d = %d\n", N, i, N*i);
System.out.println(+N+" x "+i+" = "+N*i);
}
scanner.close();
}
}
Sample Output
2
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
