This program uses the Binomial Theorem to expand the expression : (a+b)^n N can be any integer(non-decimal number)but the program cannot render the answer for answers with more than 300 characters, so you can "See Inside" and look at the variable"Ans:" or the list"Ans" After the answer is displayed, you can change the text size and press "render Text" to render the text again in your set text size
