# Numerical Answer
## Numerical Answer
In this section, students will be provided with a text box to answer the question numerically. They can only input numerical values.
There are three main formats for creating a Numerical Answer question:
1. **Exact Answer** : This is the primary answer that is calculated accurately. The precision can be specified by determining the allowable margin of error.
2. **Answer in the Range** : The answer falls within a specified range, with values ranging from the first number to the second number.
3. **Answer with Precision** : It is recommended to use the primary answer format, which is the Exact Answer.
### Creating Numerical Answer
In the section of creating this question, you can attach a picture of a complex equation or add special symbols in mathematics and science. To do this, click on the symbol 
(Insert Match Equation), and a window will appear as shown in the image below.
### The Display Page of Numerical Answer (student's view)
When responding with letters, the system will display the message "Only numerical values are accepted".
