Math Signs

I'm looking for real math symbols that I can add to my toolbar that show the math symbols we learned in school. For example instead of seeing 2*2= 4 in a cell it will show 2x2=4, so forth and so on. Is there a download available that does this function?

You can do this manually by entering numbers interspersed with operator symbols (Insert > Symbol), and then edit the character string to apply the Symbol font to the operator symbol characters. That's a nuisance.

You could not use a form just to insert the symbols as you typed into a cell, because when Excel is in Edit mode, it doesn't listen to anything else.

I think you would need to use a form that has buttons (for both numbers and operators) that builds an expression string in a text box, and then moves it to the worksheet.
