WHAT IS RPN?RPN (Reverse Polish Notation) is a mathematical notation that allows users to solve problems by mimicking how they learned to do math on paper. The operators (+,–,x,÷) are placed after the arguments (for example, 3+4 becomes 3 {ENTER} 4 +) allowing users to stack number sequences and operations, working from the bottom up. RPN eliminates the need for parentheses in complex calculations and reduces keystrokes, making problem solving quicker and more effi cient.Pressing an operator key (+ - x ÷) always 34 STEP 1:REGClear Registers (if new calculation; otherwise if part of longer previous calculation, don’t clear)STEP 2:Input initial amount, change sign and store as PVSTEP 3Input interest rate of 3, store as i%STEP 4: Solving a Basic TVM ProblemWhat is the Future Value of $50 invested today at 3% interest for 5 years?
