❗ Important note: this evaluation type only works properly if
the domain in Definition field and student’s answer are written in disjunctive normal form.
Example Definition field: x>3 and x<10 instead of 3<x<10
Example student’s answer:
instead of
or
If you want students to also be able to answer using interval notation, you can use the evaluation type eval interval.
the order of the expressions in the Definition field and the student’s answer is
variable operator numberand notnumber operator variable.
Example Definition field: x>3 and x<10 instead of 3<x and x<10
Example student’s answer:
instead of
only one variable is used.
The options for operators are:
Operator | use in Definition field | use in student’s answer |

| = |
not equal |
| ≠ |
greater than |
| > |
