Order of priority of operations

The calculation operations are completed according to the following order
of priority.
1 Coordinate conversion: Pol (x, y), Rec (r,
2 Type A functions:
In the case of these functions, the value is entered first and then the
function key is pressed.
3 2 -1

3 Powers and roots: ^(x

5 Abbreviated multiplication format in front of , e (basis for natural
logarithms), memory name or variable name: 2, 3e, 5A, A etc.
6 Type B functions:
In the case of these functions, the function key is pressed first, then
the value is entered.

7 Abbreviated multiplication format in front of type B functions: 2 3,
Alog2 etc.
8 Permutation and combination: nPr, nCr
9 x, 
10 +, −
Operations which have the same priority are completed from right to left.
¥In 120 ³ e
X
Other operations are completed from left to right.
Operations set in parentheses are performed first.
If a calculation contains an argument which is a negative number, the
negative number must be enclosed in parentheses. The negative sign ()
is treated as a type B function so that special care must be taken when the
calculation contains a type A function with high priority or power or root
operations.
