The math engine can perform advanced operations such as the addition of Vectors, determinants of Matrices. The evaluation can recognize equivalent forms, consider a primitive example: if the expected answer is 2+4 and the student enters 3+3, this will grade as correctly. If the intention is for a more precise type of answer, then you need to use the "advanced options", or the "Literal" checking mode.

**Vectors:**

Vectors in *component* form can be entered with triangle brackets on the keyboard, e.g.

You can also create vector equations as answers, .e.g.

<1,2>+<2,3> = <3,5>

Or enter them symbolically with the full keypad as follows:

Vector questions can also be created in graphing mode, for example:

Draw the following vector:

<1,2>

In preview mode, the following is an example of an incorrect student answer:

While these are correct answers:

or at other coordinates:

You can also enter vector expressions like this:
