But how would you prevent students to remove one of the * of +? When writing expressions in an inputbox they aren't calculated as you see in screenshots below. Isn't this what you want (except the interdiction to remove the + or * signs)? So yes in inputboxes expressions aren't reduced, but of course they are in the inputbar (I guessed this was your question). ]]>

It works as well in Classic 5 and 6 and I'm working now in version 609. Don't forget to check the option Symbolic in the Algebra tab of the input box. This is a Version 6 screenshot. ]]>

In this version I still get 6 * 4 when writing 2*3*4 in a input box that is connected with a function and set to Symbolic. So for me it seems it haven’t been changed in this version... Also as I can’t write it in my other post called “Show * between letters”, I can add that it is possible, but only when the letters doesn’t match defined variables.]]>

Fri, 16 Oct 2020 18:01:33 +0000<![CDATA[I have just downloaded and installed the latest version of GeoGebra 5 Classic in Windows 10 and tried to write 3^2 - 4 * 2 * 3 in a input box which is set to Symbolic. When the input box is connected with a number variable, 3^2 - 4 * 2 * 3 is shown in the input box. But in the Algebra view, the value of the variable is -15. And this cannot be used to check if a student has inserted the integers correctly in a formula as the student just could write the correct result. If instead the input box is connected to a function variable, 9 - 24 is shown in the input box. When wanting GeoGebra to check if a student has correctly substituted letters with integers in a formula, the content of the connected variable has to be the same as the shown content in the input box. I would therefore very much appreciate if you somehow could make it possible. A solution could be to make a special formula variable or make it possible to choose an option so that the expression of a number or function variable won’t be reduced.]]>
