### Algebra Questions – Further Examples

This section has algebra questions with solutions for you to study.

It provides the formulas you need to know and study in order to calculate absolute values, combinations, permutations, functions, and basic algebraic expressions.

Have a look at the formulas below. You may want to make a note of them on a piece of paper.

Alternatively, you might like to print out our **cheat sheet**, which shows the formulas most commonly used on the math section of the exam.

Then go to the algebra questions in the **free sample of our download** to check your progress with the practice test questions.

#### Absolute value:

Absolute value is always a positive number. | − *x* | = *x*

#### Combinations and permutations:

The amount of combinations of sets of S that can be made from a group containing N items can be calculated using this formula:

(N!) ÷ [(N − S)! × S!]

You need use this formula to calculate the amount of permutations of size S taken from N items:

N! ÷ (N − S)!

#### Logarithmic functions:

Logarithmic functions are just another way of expressing exponents.

*x* = log_{y}Z is always the same as: y^{x} = Z

### FOIL Method:

The use of the FOIL method is one of the most important things you will need to know in order to answer many algebra questions.

Look at the example algebra question below on the FOIL method.

Example: (3*x* − 2*y*)^{2} = ?

When you see practice questions for algebra like this one from our sample test, you should use the FOIL method.

This means that you multiply the terms in the parentheses in this order:

First − Outside − Inside − Last

Now study the solution below so that you know how to answer algebra questions like this one.

(3*x* − 2*y*)^{2} = (3*x* − 2*y*)(3*x* − 2*y*)

So, the first terms in each set of parentheses are 3*x* and 3*x*: (**3 x** − 2

*y*)(

**3**− 2

*x**y*)

FIRST: 3*x* × 3*x* = 9*x*^{2}

The terms on the outside are 3*x* and −2*y*: (**3 x** − 2

*y*)(3

*x*−

**2**)

*y*OUTSIDE: 3*x* × −2*y* = −6*xy*

The terms on the inside of each set of parentheses are −2*y* and 3*x*: (3*x* − **2 y**)(

**3**− 2

*x**y*)

INSIDE: −2*y* × 3*x* = −6*xy*

The last terms in each set are −2*y* and −2*y*: (3*x* − **2 y**)(3

*x*−

**2**)

*y*LAST: −2*y* × −2*y* = 4*y*^{2}

All of these individual parts are put together for your final answer to the algebra question:

9*x*^{2} − 6*xy* − 6*xy* + 4*y*^{2} = 9*x*^{2} − 12*xy*^{2} + 4*y*^{2}
