3. 20-(5x2). The answer is 10. [20-(5x2) -> 20-10=10]
4. B (Parenthesis are needed) and C (Start with simplifying the bottom).
5. 6x(9-3). The answer is 36. [6x(9-3) -> 6x6=36]
6. 10 divided by the difference of 6 and 4.
7. B
8. (5+7)x3 -> 12x3=36
We look for pairs of numbers in order to further simplify certain unsimplified square roots. For example, the square root of 20. From this, we pull out a 5 and two 2’s, Since there is a pair of 2’s, we carry one out, and since the 5 is not a pair, it stays inside of the radical. Therefore making it 2√5.
