instead of symbol of "square root" symbol "sqrt" is being displayed! and same is for other smblols.
Hey!
I didn't get, what your asking. But I would like to tell you that as there are abbreviations for different words in English (such as ex. - example, i.e. - that is, imp. Important, etc.), similarly there are abbreviations/symbols for different terms of mathematics such as sqrt for square root, det. For determining, A. P. for arithmetic progression, etc.
Thank you.
