Parentheses
On a Casio calculator you can enforce an order in the operation by using parentheses
( and )
or via the CATALOG as
CATALOG P INPUT CATALOG P INPUT SHIFT 4 ( F1 and SHIFT 4 ) F1
Example 1
To calculate (-2)4 = 16 where parentheses are needed
(-2)4 ( (–) 2 ) ∧ 4 EXE 16
as −24 = −16
-24 (–) 2 ∧ 4 EXE -16
Example 2
To convert cartesian coordinates (x = 1, y = √3) to polar coordinates (r = 2, θ = 60°)
Pol( √ r ≣ 1 ٬ SHIFT x² 3 EXE Pol(1,√3 {2,60}
where the right-hand parenthese may be omitted.
Example 3
To calculate 4 × 7 as 4 (7) = 28
4 ( 7 EXE 4(7 28
Example 4
To calculate (-1)0 = 1
(-1)0 ( (–) 1 ) ∧ 0 EXE 1
but be careful, because -10 = -1
-10 (–) 1 ∧ 0 EXE -1
Example 5
To calculate | 2 − 7 | × 2 = 10 with line-input as
Abs ≣ ( 2 − 7 ) × 2 EXE Abs(2-7)×2 10
