GED Math Practice Questions
One of the best ways to test your knowledge is by taking a practice test. Evaluate your math skills by trying your hand at the three practice questions below!
Answer each question and read through the answer explanation, whether you got the answer right or wrong. This will help you ensure you’ve got the topic mastered.
Whether you struggled with these questions or aced them on your first try, be sure to take the full math practice test to get a better idea of how prepared you really are!
1. A combination lock uses a three-digit code. Each digit can be any one of the ten available integers 0–9. How many different combinations are possible?
\(P=P_1 \times P_2 \times P_3=10 \times 10 \times 10=1{,}000\)
This result makes sense when we consider trying every possible code in sequence, beginning with the combinations 0-0-0, 0-0-1, 0-0-2, etc. In ascending order, the last three-digit combination would be 9-9-9.Although it may seem that there would be 999 possible combinations, there are in fact 1,000 when we include the initial combination, 0-0-0.
2. What is the surface area of a cube, in square inches, if the length of one side of the cube is 3 inches?
\(A=6\times 3^2=6\times 9=54\)
Therefore, the surface area of the cube is 54 in2.3. What is the factored form of the expression below?
\(3x^2+4x-15=(\:\:\:)(\:\:\:)\)
First, determine what goes in the first part of each set of parentheses. Since the leading term is \(3x^2\), the first terms of the binomials should be \(3x\) and \(x\). Put these terms in each of the first parts of the sets of parentheses.\(3x^2+4x-15=(3x\:\:)(x\:\:)\)
Next, determine what numbers multiply to –15 and will make the middle term of the multiplied expression equal to \(4x\).\(3x^2+4x-15=(3x-5)(x+3)\)
Notice that it is important to make sure –5 goes in the left set of parentheses and +3 goes in the right set of parentheses. If they were switched, using the FOIL method on the two binomials would result in \((3x+3)(x-5)=3x^2-12x-15\), which is not the desired expression. Therefore, the correct factorization of the expression is \((3x-5)(x+3)\).GED Math Fact Sheets

How long is the GED Math Test?
The GED Math Test is 115 minutes (1 hour and 55 minutes).
What type of math is on the GED Test?
The mathematical reasoning section of the GED test consists of two types of problems, quantitative problem-solving and algebraic problem-solving.
How much is the GED Math Test?
The cost of the GED Math test varies by state and testing format.
Can you use a calculator on the GED Math Test?
On the first section of the GED Math Test, you are not allowed to use a calculator. An onscreen calculator is available during the second part. If you test at a test center, you may also bring your own TI-30XS calculator, but doing so is optional.
How many questions can you miss on the GED Math Test?
There is no single number of questions you can miss and still pass. You must earn a scaled score of at least 145 on the GED Math test.
How many times can you retake the GED Math Test?
Retake rules vary by state and testing format. At a test center, you can generally take a subject test three times before a 60-day waiting period applies. A 60-day wait also applies between subsequent attempts. Online testing generally allows two attempts before a 60-day wait.
What do you have to score to pass the GED Math Test?
To pass the GED Math Test, you must earn a score of at least 145. The highest score is 200, and anything below 145 is considered failing.
