# Math Formulas That are Important for ASVAB

## Math Formulas That You Must Not Forget

The ASVAB is a test that serves as a gateway for all those candidates across the United States who are keen to join the military services or the Armed Forces of this country. However, the test is divided into different sections or subtests pertaining to varied subjects that are based on the standard of high school education. As a matter of fact, the ASVAB is administered to high school and post secondary students.

__Brief Overview of Mathematics Knowledge__

Although, the subtest on Mathematics is not very difficult, a
majority of applicants are jittery and anxious while tackling the
problems of Mathematics Knowledge. However, those candidates who have
scored consistently well in Mathematics while studying in high school
should not find this section too difficult. On the other hand, those
who are not confident enough while finding solutions to the problems of
Mathematics should focus on sufficient preparation for obtaining good
scores in this section. For this, they should remember the various Mathematical formulae in order to ** answer** all the

**. The questions in this section are based on Algebra, Rounding, Numbers, Interest Calculation, Fractions and Exponents.**

*16 questions within the duration of 20 minutes*Besides remembering the formulae,
the most viable solution for tackling this subtest with confidence is
to follow rigorous practice before the arrival of the date of final
examination. In fact, the ** subtest on Mathematics Knowledge is
important as the score of this section is included in AFQT or Armed
Forces Qualifying Test that determines the ability of the candidates
for enlistment in Army, Navy, Marines and the Armed Forces**.
The Mathematical formulae should not be forgotten because the
candidates are not allowed to use calculator or similar devices on the
day of the test.

__Math formulas for ASVAB Subtest__

The following Math formulae should not be missed by a candidate while taking this the ASVAB math subtest:

: a²+b²=c² in which a and b refer to the two arms of the right angle and c is the length of the hypotenuse of the right triangle.*Pythagorean Theorem*: d=2r in which r is the radius of the circle.*Diameter of a circle*: r=1/2 d in which d is the diameter of the circle.*Radius of a circle*: πr²*Area of a Circle*: 2πr*Circumference of a Circle*: p=2l + 2w in which l refers to the length and w is the width of the rectangle.*Perimeter of a Rectangle*: a=lw*Area of a Rectangle*: p=4s in which s refers one side of the square.*Perimeter of a Square*: a=s²*Area of a Square*: p=s*Perimeter of a Triangle*_{1}+s_{2}+s_{3}, in which s refers to the length of each side of the triangle.: a=1/2bh where b is the length of the base of a triangle and h is the height of the triangle.*Area of a Triangle*: v=s³*Volume of a Cube*: v=πr²h where r is the radius of the cylinder and h is the height of the cylinder.*Volume of a Cylinder*

__Tips for Taking Mathematics Knowledge__

In order to find solutions to the Mathematical problems, the candidates taking ASVAB should follow certain strategies for enhancing their scores in this section of the test:

- During the final examination, the test takers must utilize the rough paper that is provided to them for making the calculations and selecting the correct answer. However, computing the answers will be easier and faster if they remember the different formulae.
- For those problems that are difficult or complicated, the candidates should try to select the answer that is close and then calculate the correct answer.
- There are some problems in this section that are apparently tricky for the test takers. However, the answer should be calculated with the help of the information that is required for the same and the rest should be discarded.

The easiest way of tackling the questions on Mathematics Knowledge is through regular practice, although remembering the various formulae is essential. In fact, an applicant will get an opportunity to remain ahead of his competitors and obtain an enlistment in his favorite wing of the military services in the United States if he is able to secure good scores in this subtest of ASVAB.
