In this way it is much easier for the students to find an error in their calculation and correct it without the need of a teacher to do the same. And in this way the teacher get more time to help students with other problems.]]>

If you now make an inputbox for f and mark it as symbolic, it will show the formula. Now students can replace the letters a, b or c by whatever number, that's no problem. So I guess that's what you wanted. You can do it also in GG5. chris ]]>

The idea is to have a formula like for example “b^2 - 4 * a *c” written in a input box where the students just have to substitute the letters with numbers. The reason for this is to make it easy for the student to insert integers in the formula and to get GeoGebra to check if they have inserted the integers correctly in the formula. At this moment when you create an input box and write “b^2 - 4 * a *c” in it, then “b^2 - 4ac” will be written in it. And if the students just substitute the letters with integers without writing “*” in between a and c, then GeoGebra will stall. Therefore I suggest to make it possible to get “•” written between letters in an input box. This can for example be done by adding an option to the properties of an input box: “Show • between letters”.]]>
