• Operations of the same precedence are performed from right to left. exIn 120 → ex{In( 120)}

•Other operations are performed from left to right.

•Operations enclosed in parentheses are performed first.

•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 operations.

Example: ( –2)4= 16

–24= –16

kStacks

This calculator uses memory areas, called “stacks,” to temporarily store values (numeric stack) and commands (com- mand stack) according to their precedence during calcu- lations. The numeric stack has 10 levels and the command stack has 24 levels. A stack error (Stack ERROR) occurs whenever you try to perform a calculation that is so complex that the capacity of a stack is exceeded.

•Matrix calculations use up to two levels of the matrix stack. Squaring a matrix, cubing a matrix, or inverting a matrix uses one stack level. (fx-570MS, fx-991MS only)
