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(, 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, x3, x-1, x!, °’ ”, °, r, g, %), powers (), roots ()
4	Fractions
5	Negative sign ((-))
6	Statistics Mode estimated values (xˆ, yˆ, xˆ1, xˆ2)
7	Multiplication where the multiplication sign is omitted
8	Permutation (nPr), combination (nCr)
9	Multiplication (×), division (÷)
10	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
