Simple Algebraic notation is an input logic that uses neither operator precedence nor parentheses when performing calculations. It is a form of infix notation. In simple algebraic notation, the binary operators are between their operands. For example, to add two and three, you would enter [2] [+] [3] [=].
Simple algebraic notation is similar to the way calculations are written on paper, but without operator precedence. Let's see how it works for a simple calculation. For this example, we'll calculate 4 + 2 x 3 - 5:
Using simple algebraic notation, click/press [4] [+] [2] [x] [3] [-] [5] [=]. Since there is no operator precedence, the calculation is performed in the order in which it is entered, for the answer, 13.
[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.
