FREE Reverse Polish Notation Sample | AQA A Level Computer Science 7517 | 2 Worksheets + Answers

Two free sample worksheets on Reverse Polish notation for AQA A Level Computer
Science (7517), with full answer keys, so you can see exactly what the full
pack contains before buying anything.

Each sheet converts an infix expression to RPN, converts a different RPN
expression back to infix - the “and vice versa” the specification asks for -
and evaluates an RPN expression with a stack, one row per token read. The last
question asks why RPN needs no brackets.

Precedence, the order of the operands of a subtraction and which end of a
written stack is the top are all stated on the sheet, so each question has one
correct answer.

These two sheets are not in the paid pack - they are extra, so nothing is
wasted if you buy it afterwards.

The full pack contains 20 worksheets and 20 answer keys, every one on
different expressions. Search Tes for “AQA A Level Computer Science reverse
Polish notation” to find it.
