Order of operations

On a Casio calculator the operations are performed in the following order of precedence.

  1.  Coordinate transformation: Pol(x, y), Rec(r, θ)
  2.  Type A functions:
with these functions, the value is entered and then the function key is pressed.
x3, x2, x-1, x!, ° , ,,
, , 1, 2
Angle unit conversion ()
  3.  Powers and roots:
^(xy),
  4.  ab/c
  5.  Abbreviated multiplication format in front of π, e (natural logarithm base), memory name, or variable name: , 3e, 5A, πA, etc.
  6.  Type B functions:
with these functions, the function key is pressed and then the value is entered.
 , 3 , log, ln, ex, 10x, sin, cos, tan, sin-1, cos-1, tan-1, sinh, cosh, tanh, sinh-1, cosh-1, tanh-1, (−)
  7.  Abbreviated multiplication format in front of type B functions: 2√3, Alog2, etc.
  8.  Permutation and combination: nPr, nCr
  9.  ×, ÷
  10.  +,
  ∗  Operations of the same precedence are performed from right to left. exln√120 → ex {ln(√120)}
  ∗  Other operations are performed from left to right.
  ∗  When a calculation contains an argument that is a negative number, the negative number must be enclosed within parentheses. The negative sign (−) is treated as a type B function, so particular care is required when the calculation includes a high-priority type A function, or power or root operation.

Example:                  (-2)4 = 16
                                            -24 = -16
