Technical Information
Calculation Priority Sequence
The calculator performs calculations according to a calculation priority sequence.
When the priority of two expressions is the same, the calculation is performed from left to right.
1 | Function with parentheses: Pol(x, y), Rec(r, θ), differentials (d/dx), integrations (∫dx), normal distribution (P(, Q(, R() |
---|---|
2 | Type A functions: With these functions, the value is entered and then the function key is pressed. (x3, x2, x-1, x!, ° ’ ”, xˆ, xˆ1, xˆ2, yˆ, t, °, r, g, engineering symbols, metric conversions*) (*fx-570MS/fx-991MS only) |
3 | Powers and roots: xy, x√ |
4 | Fractions |
5 | Implied multiplication 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, (-), d, h, b, o, Neg, Not, Det*, Trn*, arg, Abs, Conjg) (*fx-570MS/fx-991MS only) |
7 | Implied multiplication of Type B functions: 2√3, Alog2, etc. |
8 | Permutation (nPr), combination (nCr), complex number polar coordinate symbol (∠) |
9 | Dot product (•) (fx-570MS/fx-991MS only) |
10 | Multiplication, division (×, ÷) |
11 | Addition, subtraction (+, -) |
12 | Logical AND (and) |
13 | Logical OR, XOR, XNOR (or, xor, xnor) |
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 operations.
Example: (-2)4 = 16; -24 = -16
