                      Algebraic expressions

                      Reading time: 1min

                      There are several notation considerations you need to take into account if you want to create an algebraic expression through the code editor. As you can see in the screenshot below, CalcMe will interpret expressions beginning with an alphabetic character as an identifier (in blue), like a reserved word.

                      This behaviour can involve some validation problems in a WirisQuizzes question context, given that E·13≠E13.

                      Thus, to avoid these situations, there are two workarounds you can use indistinctly. We recommend using the first one, as you can keep generating the algorithm within the code editor, but both are equally possible.

                      • Insert the dot operation product between all alphabetical characters and numbers.

                      • Define such expressions inside CalcMe.
