The inputs above will be hidden when the program finally gets launched. Currently, I am not hiding them even when you close the calculator. The purpose of the inputs is to help in debugging. This allows you to enter simple code on the calculator screen but the program translates the input to javascript math. Give it a try and see if you notice any obvious problems or have suggestions for improvements.

Enter expression to evaluate here:

The answer is shown below:

Enter function to be plotted:

f(x) =

Enter 2nd function, if needed:

g(x) =

Change or reset the x-y scaling below:

y_max =

Accuracy Disclaimer

The javascript math object methods used for this calculator are not accurate for very large or very small numbers. In particular, the trigonometric functions may yield very small answers that should actually be zero or very large answers that should be infinite. This typically occurs at 90° or pi/2 intervals.

DO NOT USE WHERE HIGH PRECISION IS REQUIRED. USE AT YOUR OWN RISK.

GED Answer Grid Help

It is very important that you know how to fill in the bubbles on the answer grid shown on the left because 8 of the 50 math problems must be answered using a similar grid.

This particular grid has been automated showing you the numbers at the top of the grid as you click on a bubble. It will not let you mark more than one bubble in each column nor will it allow spaces between digits. The only thing that counts on the exam is the bubbled in values.

On you GED test sheet you will have to write the numbers at the top of the grid and fill in the bubbles. Be very careful, not to fill in more than one bubble in any individual column and do not leave spaces between the digits.

Note: You can enter decimal numbers or fractions. Do not enter mixed numbers, e.g. 2¼ should be shown as 9/4. Also, do not enter zeroes in front of whole numbers. All fractional answers must be reduced to lowest terms.

Fill in some bubbles to see the result. Remember to reduce all fractions.
