Calculation 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 Parenthetical expressions
2 Functions that have parentheses (sin(, log(, f(, g(, etc., functions that take an argument to the right, functions that require a closing parenthesis after the argument)
3 Functions that come after the input value (x2, x-1, x!, °’ ”, °, r, g, %), powers (), roots ()
4 Fractions
5 Negative sign ((-))
6 Statistics app estimated values (xˆ, yˆ, xˆ1, xˆ2)
7 Multiplication where the multiplication sign is omitted
8 Permutation (nPr), combination (nCr), complex number polar coordinate symbol (∠)
9 Dot product (•)
10 Multiplication (×), division (÷)
11 Addition (+), 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 3, above), whose priority is greater than the negative sign, which is a prefix symbol (Priority 5).


Example:

((-))2    -22 = -4

((-))2 (-2)2 = 4
