Order of operations
On a Casio calculator the operations are performed in the following order of precedence.
| 1. | Coordinate transformation: Pol(x, y), Rec(r, θ) |
| 2. | Type A functions: with these functions, the value is entered and then the function key is pressed. x3, x2, x-1, x!, ° , ,, x̂, ŷ, x̂1, x̂2 Angle unit conversion (  ) |
| 3. | Powers and roots: ^(xy), |
| 4. | ab/c |
| 5. | Abbreviated multiplication format in front of π, e (natural logarithm base), memory name, or variable name: 2π, 3e, 5A, πA, etc. |
| 6. | Type B functions: with these functions, the function key is pressed and then the value is entered. √ , 3√ , log, ln, ex, 10x, sin, cos, tan, sin-1, cos-1, tan-1, sinh, cosh, tanh, sinh-1, cosh-1, tanh-1, (−) |
| 7. | Abbreviated multiplication format in front of type B functions: 2√3, Alog2, etc. |
| 8. | Permutation and combination: nPr, nCr |
| 9. | ×, ÷ |
| 10. | +, − |
| ∗ | Operations of the same precedence are performed from right to left. exln√120 → ex {ln(√120)} |
| ∗ | Other operations are performed from left to right. |
| ∗ | When a calculation contains an argument that is a negative number, the negative number must be enclosed within parentheses. The negative sign (−) is treated as a type B function, so particular care is required when the calculation includes a high-priority type A function, or power or root operation. |
Example: (-2)4 = 16
-24 = -16
