Text
Students can answer with plain text, removing any mathematical comparison. You need to select the Text answer type for pure text answers with no mathematical content.
Validation options
There are several particular validation options when we create a Text question.
Note you can set:
Match case: if disabled, lowercase and uppercase letters are equivalent.
Match spaces: if disabled, leading and trailing spaces will be removed, and internal groups of spaces will be collapsed to one.
Random variables
If the correct answer is generated using CalcMe, it must be a string. To convert an expression to a string you can use:
Make a constant string:
a="123"Concatenate with a string, even the empty one:
b=123|""string(123)string_substitution("#1",123)
If you are using the string_substitution() command, it's essential to consider that mathematical expressions can't be introduced through the code editor. You can find an example below:

Example: Converting a number to hexadecimal
Imagine creating a question asking to convert a given random number to hexadecimal. To do so, we need to start creating the CalcMe algorithm where we're going to define than random decimal value and the corresponding hexadecimal representation.
Thus, the variable will correspond to the correct answer to the question. We need to define it in WirisQuizzes Studio accordingly.
As we want to accept both answers in capital or lowercase letters, but we want the answer to have exactly 8 digits, we will select the following validation options:
Once saved the changes and assigned the full grade to the correct answer, we can preview the question to see how it works.
