There are eight types of **Math** questions that can be created.

Expression & Formula is the most general authoring mode, and Numeric Entry is the second most common mode.

Many of these are the same for authoring, so here is a general outline.

Step 1. Enter the **question text**.

If you want to add a mathematical expression, like square root in the screen above, you need to use Edit Math editor. To open it, press the button **Math**.

Here, in the Edit Math window, you can type any mathematical expression using keyboard, keypad buttons, or directly by inputting LaTeX code.

After pressing the **OK** button the expression will be inserted into the question text.

Step 2. Enter the **points** and the **answer**.

**POINTS** are obviously the grade a student would get if his answer would match your **EXPECTED ANSWER**.

Step 3. Preview how your question works.

This step is optional, but we **highly recommend** to check the evaluation by using the **Preview mode**.

A student can input terms in a different order, for example, (6+x) instead of (x+6), and all such inputs will be accepted, if they are equivalent to the correct answer defined by a question creator

If you want to change such Edulastic behavior, you can use **ADDITIONAL OPTIONS** below the correct answer input box. For example, if you check in the option **Check if expression is simplified**, Edulastic will no longer accept the expressions like 5-2 instead of 3. (however, it will proceed to accept 6+x instead of x+6 since both of them are equivalent and simplified)

More information on these options.

*Note: for simplified expressions with variables, try to avoid using any variables that could be incorrectly interpreted as units, e.g. 3x + s + m + 2. Here the evaluation may interpret the s as seconds and m as minutes. *

Step 4. **SAVE** and then **PUBLISH** your question.

Please pay attention that you can edit your question anytime after you save it, but you **CAN NOT edit the question** **after you publish it**.

If you accidentally publish your question and, for example, find a mistake in it and want to want to edit (as I also sometimes do), the only way is to make a duplicate of your question (button **CLONE** in **Item Bank / View** window), edit/save/publish the new question, and then remove the old question.

To make questions with random content as a way to discourage cheating you can use Dynamic content.
