Challenge 1

Create a multiplication table using a nested for loop. The table output should look like this:

Multiplication Table

1 x 1 = 1 
1 x 2 = 2
1 x 3 = 3
1 x 4 = 4
1 x 5 = 5
1 x 6 = 6
1 x 7 = 7
1 x 8 = 8
1 x 9 = 9
1 x 10 = 10
and so on...

Challenge 2

Get the sum of the numbers in an array by using a foreach loop and for loop.

$numbers = [1, 2, 3, 4, 5]; //sum using foreach loop
$numbers2 = [1, 2, 3, 4, 5,6,7,8,9,19]; //sum using for loop

Sample Output

Sum array using foreach loop
15
Sum array using for loop
64

Challenge 3

Calculate the average students grade from an array of students. Each student has their own array with the key grades.

1. Create an array of students with their names and grades (0 - 100)
   john 85, 90, 92, 88
jane 95, 88, 91, 87
joe 75, 82, 79, 88
   

2. Iterate over the students array with a foreach loop

3. Calculate the average grade for each student.

Sample Output

Average Grade 
John: Average Grade = 88.75 
Jane: Average Grade = 90.25 
Joe: Average Grade = 81
