| Basic Arithmetic Operations |
| + | Addition. |
| - | Subtraction. |
| * | Multiplication. |
| á | Division. |
| = | Performs the calculation and displays the result. |
| +/- | Minus sign - Changes positive numbers to negative and vice versa. |
| ( ) |
Parentheses are used to change the order of operations in an expression or to pass a parameter to a function. Example: (3 + 2 ) × 5 = 25 |
| Ȩ |
Exponent - Enters a number in exponential form. Example: 3E5 = 300000 |
| ș |
Repeating Decimal - Sets the repeating decimal portion of a number. To indicate a repeating decimal part, enclose the repeating digits in curly brackets. The repeated part is shown at the display by a Vinculum notation (overline).
Example: enter 0.02{27} is equal to 0.0227272727272727... (1⁄44) |
