Solve this using order of operations:
2 exponent 2 x 9 / 3
Exponent 2x2 or 2 squared = 4
Multiplication 4x9/3 = 36/3
Division: 36/3 = 12
Add 2/3 + 3/6
Find a common denominator (6).
to get from 3 to 6, you must x 2 (denominator) and now you must x 2 to the numerator (top number).
2 x 2 = 4 4/6 + 3/6 (common denominator), now simply add numerators: 7/6 or 1 and 1/6

Using PEMDAS, solve for the following:
(3-1) x 4 + (6x2)
First solve within parenthesis:
(2) x 4 + (12)
Next multiply:
2 x 4 = 8
8 + 12 = 20
Subtract 8/10 - 4/10
They had the same denominator. Thus, you can simply subtract numerators (8-4) = 4
4/10 simplifies to 2/5
