unnecessary.

When rationalizing fractions

or simplifying radicals, there

is always a radical symbol and

a denominator provided in the

answer form, even if it is

Student Confusions

When solving different

kinds of equations,

students are often

presented with the

option to enter

multiple solutions, even if

there is only one.

Format

Students are marked incorrect if they enter "X" rather than "x" for their solutions.

When factoring polynomials, students may be marked incorrect based on the order that they write the factors, even if they are correct.

Teacher Complaints

If you have more than one class on Delta Math, the student data page initially displays each class, along with all of the assignments for each class.

In order to look at just one class, you need to scroll through the classes.

(First World Problems)

Delta Math often uses formulas and notation that the teacher does not use.

Delta Math may or may not display student

names alphabetically, depending on which

browser you use.

Fire Fox does display names alphabetically,

but Google Chrome does not.

Graphing

You can only have two functions on this calculator!

There is an apparent glitch when students are asked to draw a graph*. You need at least two points for a line, but the calculator sometimes doesn't process that students have, in fact, plotted two points. In frustration, they keep choosing points, and then receive an error message that they have too many points.
