## GED Math Study Guide

The GED Math syllabus includes a range of math topics; however, you are not required to get familiar with Advanced Mathematical Concepts such as trigonometry or calculus.
Below you will find a full list of topics that appear on the GED Math Test.

### Pre GED Math

Prerequisites for success on the GED Math test and to follow online GED classes are knowledge of basic operations such as addition, subtraction, multiplication, and division of whole numbers.

Even though you can use a scientific calculator during the second part of the GED Math test, understanding these basic math operations is essential.

To check your knowledge, take our Pre GED Math Practice Test.

Next, you should get familiar with the math topics that are included in the GED Math Test.

### Number Sense

Number sense questions ask for solving math problems related to:

• Ordering numbers on a number line, that includes positive & negative numbers, fractions, and decimals.
• Rounding and estimating numbers.
• Calculating ratios, proportions, and percent.
• Calculate exponents, convert fractions to decimals, and vice versa.
• Applying the order of operations rules ( PEMDAS).

These topics are not complex, and you can use a provided scientific calculator to solve the majority of these questions.

We will show you how to do it later on.

### Geometry

• Area and perimeter of squares, triangles, and circles.
• The volume of a prism, cone, sphere, or pyramid.

Tip: You have access to Math geometric formulas, and you can solve the majority of Geometry questions by using these formulas.

### Data Analysis

Data Analysis on the GED Math Test includes topics such as

• Calculations of mode, range, mean, and median.
• Finding probability.

Tip: Use provided Math formulas and a scientific calculator to solve these questions.

### Algebra

• Evaluating algebraic expressions and polynomials.
• Solving equations with one or two variables; systems of equations.
• Solving inequalities.
• Evaluating functions.

Tip: Many Algebra questions can also be solved with the help of a scientific calculator.

### Graphing

Graphing problems include

• Coordinate plane questions (points, lines, & shapes).
• Slopes and equations of lines.

Tip: The provided Math formula sheet includes three slope formulas, so you can always use it.

### Word problems

The GED Math test includes numerous word problem questions. These questions combine many topics, such as solving equations and geometry or probability. Even though they seem to be challenging, they involve rather simple math. You only need to translate words into math.

To master the word problem-solving skills, you should take many practice tests to understand these questions’ format.

## How many questions do I need to get right on the GED math?

The GED® Math Test takes 115 minutes and has about 45 to 49 questions divided into 4 main categories.

To pass the GED Math test, you have to answer between 30 and 32 of the questions correctly. The Math questions are divided into these four categories:

• Solving Equations: 30 percent
• Graphs & functions: 25 percent
• Number Sense, Order of Operation, and Probability: 25 percent
• Geometry: 20 percent

## 10 GED Math Test Tips

These tips will help you prepare for the GED Math tests effectively.

### 1. Read all the data carefully before solving a problem

On the GED Math test, there’s quite some emphasis on Data Analysis topics. You may come across questions that have tables, charts, or graphs. Read the question carefully twice! Don’t just jump straight to a question. Take a moment to really understand the question and the data presented before trying to answer the question.

### 2. Translate word problems cautiously

When taking the GED Math subtest, be sure to understand the mathematical concepts that are underlying the question. Translate a word problem carefully and cautiously, especially because they are very prevalent on the math test.

One or two different words can change the meaning radically. There’s no need to rush these challenging math questions, even when the math seems pretty obvious to you.

Sometimes, the GED math answer options express correct answers not in their simplest form or as expressions. You may know the correct answer even though it doesn’t show in the answer options.

So when you know you’ve got the answer right and don’t see that option, try to rewrite it. If you express it in a different way, it may match one of the answer options. For instance: \$50 equals \$15 + \$35, and 52 equals 25.

### 4. Practice using a scientific calculator

On the GED math test, you’re not expected to memorize complex formulas or do complex arithmetic calculations in your head.

In part two of the GED math section, you are allowed to use a calculator. You can bring your own TI-30XS scientific calculator, but there will also be an on-screen calculator provided.

So get familiar with the on-screen GED calculator or the TI-30 XS well before taking the actual test.

This will help you ace the math test! Learn how to deal with basic functions like exponents and square roots on the calculator, and you’ll also get a reference sheet with Math Formulas to help you make it through the exam.

### 5. Time yourself

The GED subtests are all timed tests. The pressure of taking a test within a limited time frame is, for many math test-takers, a source of stress and anxiety.

You can very well manage this phenomenon by taking multiple timed practice tests. You can check your results, learn what fields need improvement, and gain self-confidence to complete the GED math test within the given amount of time.

### 6. Don’t waste time

You shouldn’t waste much time on questions that you don’t know the answer to immediately or that you are not sure about.

If you have no clue about the correct answer option, skip that question and move on to the next problem. Many test-takers feel they wasted too much time dwelling on questions they didn’t know the answer to.

When you feel you’ll need lots of time to figure out an answer, flag that question and move ahead to those questions that’ll take less time. You may always come back later and try to find the right answer.

When you’ve finished the test and have some time left, go over these questions once more, and perhaps the other questions may have put you on the right track.

Also, eliminate those answers that you think are definitely wrong and then come up with an educated guess. It’s probably easier to choose from two than from four options, right?

### 7. Eliminate obviously wrong answer options

As stated in tip #6, eliminating obviously wrong answer choices is a very useful strategy. Oftentimes, one or two of the answer options on the GED math section do not make any sense at all.

They may not refer to the provided data or be totally irrelevant. When you eliminate these obviously wrong answers, you’ll be left with a smaller number of answers which will make an educated guess considerably easier.

### 8. Simplicity is the best

Oftentimes, there’s more than one way of working around a problem. You may solve a problem, even with a given function, differently.

If you happen to see another way for solving the problem, just use it, but don’t forget to check if your answer is correct. When dealing with combined figures, remember that the rule to solve it is to do it as easily as you possibly can. The answer is always the same, regardless of how you’ll break the figure down.

### 9. Remember the Exponent Rules

When multiplying two terms with identical bases, you simply add the exponents. When dividing two terms with identical bases, you simply subtract the denominator’s exponent from the numerator’s exponent.

When a parenthesis separates two exponents, you can simply multiply the exponents. You can try to simplify an exponent by rewriting a number in terms of its exponent. For instance, 27 equals 33.

And don’t forget as well that on the GED test, there’s no penalty for guessing and wrong answers. Just be sure to answer all questions, even when you’re not sure or need to guess.

## What is the best GED study guide?

Many people choose online lessons as a way to study for the GED Math test, such as the lessons published on this website.

However, if you prefer studying from the book, there are a few well-known guides, including Kaplan and McGraw-Hill. We publish a separate article about GED books.

Summary

GED Math Test is not considered to be an easy test. Many students try to pass it multiple times.

To avoid this kind of setback, get familiar with required math topics, learn how to use a scientific calculator, and take as many practice tests as possible.

Start today by taking one of our GED Math lessons and keep going. It doesn’t matter when you left school. Everyone can pass the GED Math test, so can you.
