# Math and Formula

The Math Formula question allows students to easily enter complex math as a response, with advanced validation capabilities using math specific scoring methods, in conjunction with our purpose built math engine.

## Create a Question

Enter the question stem in the **Compose Question** area. If you want to insert some math in the stimulus, you can use the Math Editor. *Note* that the student will not be able to interact with math entered this way. To access the Math Editor, click inside the Compose Question text area and select **Math Editor** from the **Rich Text Editor** panel (see *Figure 2*).

A new window with a keypad will pop up and you will be able to add a **LaTeX** or MathML expression. *Figure 3* shows an example.

Student response boxes (and math expressions) are added in the **Template** area. This is a LaTeX *only* area, and math expressions and response boxes are entered using the LaTeX Keypad - as seen in *Figure 4* below.

It is important to remember that **everything** entered into the Template area must also be entered into the Value field in the validation area, or the question will not validate properly.

### Follow these steps in order to configure validation:

**STEP 1:**Insert a value in the**Point(s)**box to set the score for the question. The default value is 1.

**STEP 2:**Underneath the Point(s) area, select a suitable math**scoring method**from the dropdown menu. There are various scoring methods available in math question types. You can learn more about each of them and play with interactive examples on our [**Formula page]**. For this example we are going to choose [**equivSymbolic]**. This will accept any math that is symbolically equivalent to what the author enters in the Value field, and is the most flexible scoring method.

**STEP 3:**Now**insert the correct response**into the**Value**field. In the case below, the correct response must be in the form x+y=z and the sum of two terms must be 3/4. You only need to enter one possible solution in the Value field in order to make it work.*Remember that everything that has been entered in the Template area must be copied to the Value field in validation.*

*Figure 5 *shows validation settings for this example. EquivSymbolic also validates percentages and decimals as equivalent.

**STEP 4:**Each scoring method has**additional options**that allows authors to set more precise validation conditions. A breakdown of all options associated with certain scoring methods can also be found in our**[Formula tutorials]**. When you select a scoring method, all of its extra options will be displayed underneath the Value field.
