Overview

Algebraic notation is an input logic that uses operator precedence, and allows use of parentheses to force precedence when performing calculations. It is also known as infix notation. In algebraic notation, the binary operators are between their operands. For example, to add two and three, you would enter [2] [+] [3] [=].

Calculations Using Algebraic Notation

Algebraic notation is similar to the way calculations are written on paper. Let's see how it works for a simple calculation. For this example, we'll calculate 4 + 2 x 3 - 5:

Using algebraic notation, click/press [4] [+] [2] [x] [3] [-] [5] [=]. Since multiplication has a higher precedence than addition and subtraction, it was performed fist. After that, the addition and subtraction were performed, for the answer, 5.

Let's say we want to calculate (4 + 2) x 3 - 5 instead. Click/press [(] [4] [+] [2] [)] [x] [3] [-] [5] [=]. Since parentheses have has a higher precedence than multiplication, addition and subtraction, the calculation enclosed within them was performed fist. After that, multiplication was performed. Lastly, the addition and subtraction were performed, for the answer, 13.

Clearing the Calculation

[CE] clears only the display value. [C] clears the display value and the entire calculation. [AC] clears the display value, the entire calculation, all statistical data, and the memory.
