–2√9 =   –6           5             -8           1             2*(3)=-6

√a2 =     A             5             -8           1             a X a

5√36 =   30           15           -5           0             5 X 6 = 30

3√7 + 8√7 =         11√7      8√2        3√3        2√14


First you must add or subtract each individual square root. Once this has been done you will find the square root of each integer. Finally once you have the square root of both integers, you will then add or subtract the two to get your answer.


Example: √141 - 116 - √4

1. First subtract 141-116; your new problem will look like the following: √25 - √4

2. Next take the square root of both √25 & √4; your new problem will look like the following: 5-2

3. The final step is to calculate the simple problem 5-2=3

    This story reminded me of how I finally passed the ASVAB after failing it twice.

    What really helped me was to do lots of online practice, learn to eliminate wrong answers, and get comfortable with the time limits.

    Before I learned how to pass the ASVAB, I wasted a lot of time looking for free sample questions and study materials that didn't help me at all.

    The secret is to use the right materials and practice under the same pressure as in the real test.

    The website that helped me the most to pass the ASVAB is this one:

    Hope it helps anyone reading this!
