kCalculation Priority Sequence

The calculator performs calculations according to a calculation priority sequence.

Basically, calculations are performed from left to right.Expressions within parentheses have the highest priority.The following shows the priority sequence for each individual command.1.Function with parentheses: Pol(, Rec(

sin(, cos(, tan(, sin–1(, cos–1(, tan–1(, sinh(, cosh(, tanh(, sinh–1(, cosh–1(, tanh–1(

log(, ln(, e^(, 10^(, '(, 3'( Abs(Rnd(

2.Functions preceded by values, powers, power roots: x2, x3, x–1, x!, °, r, g, ^(, x'(

Percent: %3.Prefix symbol: (–) (negative sign)4.Statistical estimated value calculation: m, n, m1, m25.Permutations, combinations: nPr, nCr6.Multiplication and division: ,

Multiplication where sign is omitted: Multiplication sign omitted immediately before π, e, variables (2π, 5A, πA, etc.), functions with parentheses (2'(3), Asin(30), etc.)

7.Addition and subtraction: +, –

If a calculation contains a negative value, you may need to enclose the negative value in parentheses. If you want to square the value –2, for example, you need to input: (–2)2. This is because x2 is a function preceded by a value (Priority 2, above), whose priority is greater than the negative sign, which is a prefix symbol (Priority 3).
