Before taking the first part of the GED math test, the test administrators will issue you a Casio fx-260 calculator and allow you a few minutes to test and get used to it. However, using this calculator even before that when you are studying for the test and taking practice GED math test will give you a greater edge. You will already know the locations of all the keys that you will need and how to use them. Remember, though, that for half of the test you will not be able to use a calculator, so try not to become too dependent on it by making sure that everything you can do on the calculator you can still also do by hand.

This is what the calculator looks like:

You don’t need to worry about many of the keys on this calculator. The keys that you should be familiar with (besides the basic keys that are self-explanatory) are explained in the image below:

Using this calculator is pretty straightforward and after playing around with it for a little bit you should be able to do everything you will need to on the GED math test. Some of the functions you might be less familiar with on this calculator are explained below.

### Fractions

Push the fraction key before every number that is part of a fraction.

Example question:

A crew of painters can paint an entire apartment in 4 ½ hours. How much of the apartment can they paint in 2 ½ hours?

Answer:

Since you want to know what percent 2 ½ is of 4 ½ you divide 2 ½ by 4 ½, so on the calculator you enter:

You should get 5/9 and on your calculator display it will look like this:

### Parentheses

Push before the numbers in parentheses and after the numbers in parenthesis.

Example question:

Find: 41(124 ÷ 4) – 21

On the calculator enter:

You should get 1250.

Don’t understand why they are making it so hard. People can’t get jobs with out the GED and they don’t have the money to keep paying for tests they didn’t pass or the time to do this I have been working on a GED for years. Then just to go back and have to start all over again. And you go to a room to get help and they can’t even do the Math there self the ones that are there to help you out. And they say oh do the other tests and pass and then you’ll feel good about passing. Look if I can’t pass the Math this time I’m not wasting my time. I have already passed the other test before. Something needs to change. They need who ever are in the Class rooms to help you know Math and how to use the Calculator. Now they are using a different one. More and more of us are dropping out and it not all on us. All they care about is getting there grants and the teacher just sit around texting on there phone and playing on there tablets. I’m not a young person I’m 54 my teacher is 25 yrs old and has real care weather anyone passes or not. So I quit I will study on my own at home and save gas and time.

Thank you for your site. I have passed all the GED tests the first time around but the math. The same as the others have posted above. I hope I can pass it this second attempt!
