What's the point of it?

>>	Anonymous Wed Dec 30 15:22:46 2015 No.7752961 But doesn't the nuisance value of having to translate problems from textbook outweigh the benefits?

>>7752961
>problems from textbook
yes all of math has been developped to write textbooks.
In fact the jews control mathematics because they want exclusive rights to textbook publication and sell them to retarded american kids $400 a piece.
To keep selling more, they made them mandatory and are now selling textbooks at the PhD level.

Because the operator comes last, you have no issues with operator precedence, so there's no need for parentheses.

With regular infix notation, the meaning of an operator depends on a later part of the expression and you have to use the shunting-yard algorithm to parse it instead of a simple stack like with RPN.

>>	Anonymous Wed Dec 30 16:07:56 2015 No.7753051 Did abstract algebra, no RPN. Mainly group and ring theory. Thanks for responses, I'm going to play around with RPN and see how it goes
