there is a problem in the graphing, at x=5 you have to paint a dotted line.

solve([(-4*x-8*y) = 2,(2*x) = (8+4*y)],[x,y]) [enter] returns {[7/4,-9/8]}

There is one bracket too many. {[7/4,-9/8]} => [7/4,-9/8]

It would seem to me that this is due to solve returning a set of results. To keep the type of result consistent, a singleton set is returned. (If it were otherwise, and incorporated into a larger routine, that routine would have to check the type of result returned — set or no.)

For example, solve([(y^2) = 2],[y]) returns {[sqrt(2)],[-sqrt(2)]}.

When plotting, the graphics engine does not calculate the field of view, and the viewing plane is usually empty.
An automatic adjustment is necessary.

In full screen the simulator makes a bad keyboard adjustment.

Also the virtual key press effect is not displayed very well. I suggest placing a highlighted colored frame to see which key has been pressed.

The index of a root looks like a factor since the number has a very large character, other characters could be used as superindices. ⁰¹²³⁴⁵⁶⁷⁸⁹

In the definitions it is not necessary to equal them to zero.

Hello, some suggestions for improving the UI

In CAS Mode almost no ► operator is used to store data, the most common is :=, so I propose for the next update a menu with assignment operators.

Another simple, but significant improvement is that to display the cursor in the expression entry bar you have to press the cursor key up and then press it down again. To go to the expression editing bar first, it would be sufficient to press the cursor up key.
