I've seen students get hung up with this issue numerous times, usually with some arithmetic operation. So instead of

∫x²dx +5 ie, ∫(x^2,x)+5

they enter

∫x²dx+5 ie, ∫(x^2,x+5)

The error is very subtle visually in Textbook mode. You'd only notice it if you knew to look for it.

The Nspire handles this by surrounding the term with parentheses whenever the expression is anything more than a single variable. So the above error looks like

∫x²d(x+5)

which clearly shows the user what is really happening.

Is there any way to get the template to do something similar? As it is, the error message tells the student that something has gone wrong, but there is no indication of what the source of the error is. The student is at a loss trying to figure out what went wrong.
