Prime Numbers: A number with exactly two factors:

1 and itself

Example: 23 has only two factors; 1 and 23

Composite Numbers: A number with more than two factors:

Example: 24 has multiple factors: 
Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24

4 x 6 = 24
2 x 12 = 24
24 x 1 = 24
8 x 3 = 24

Use BEDMAS to solve equations with multiple types of operations

Example 1) Solve 

6 x (5 + 7)

= 6 x 12

= 72

Step 1) Solve the operation in the Brackets

Step 2) Solve the next operation 
             6 x 12

Step 3) Multiply 6 x 12 = 72
