I am finding it very helpful. I would be interested in learning how to use it better, so a webinar would be helpful. We have a business account and most of our staff do not know how to use it at all yet, so a webinar would be really helpful.

I love this software and use it frequently.
Has a free trial, has many tools, easy to use and has template searching capabilities.

What do you mean by reverse Polish notation?
Reverse Polish notation (RPN) is a method for conveying mathematical expressions without the use of separators such as brackets and parentheses. This notation is suited for computers and calculators since there are fewer characters to track and fewer operations to execute.
Why is reverse Polish notation used?
Reverse Polish notation (otherwise known as post-fix, RPN for short) is a way of representing mathematical equations. The notation is used because the format that the equation is in is easier for machines to interpret rather than the notation we are used to, infix notation, where the operator is in between the numbers.
Is reverse Polish notation still used?
The description “Polish” refers to the nationality of logician Jan ukasiewicz, who invented Polish notation in 1924. During the 1970s and 1980s, Hewlett-Packard used RPN in all of their desktop and hand-held calculators, and continued to use it in some models into the 2010s.
Who invented reverse Polish notation?
Polish notation, in which the operator comes before the operands, was invented in the 1920s by the Polish mathematician Jan Lucasiewicz. In the late 1950s, Australian philosopher and computer scientist Charles L. Hamlin suggested placing the operator after the operands and hence created reverse polish notation.
What is Polish notation with example?
In this notation, operator is prefixed to operands, i.e. operator is written ahead of operands. For example, +ab. This is equivalent to its infix notation a + b. Prefix notation is also known as Polish Notation.
What do you mean by Polish notation?
Polish notation is a notation form for expressing arithmetic, logic and algebraic equations. Its most basic distinguishing feature is that operators are placed on the left of their operands. If the operator has a defined fixed number of operands, the syntax does not require brackets or parenthesis to lessen ambiguity.
