Calculates 125’.
Calculates cube root of
125, which is the same as
125'/’.
Using Parentheses in Calculations
Use parentheses to postpone calculating an intermediate result until
you’ve entered more numbers. For example, suppose you want to
calculate
30
(85 - 12)
x9
If you enter 30 0 85 0, the calculator displays the intermediate result,
0.35. This is because calculations without parentheses arc performed from
left to right, as you enter them. To delay the division until you’ve sub
tracted 12 from 85, use parentheses. Closing parentheses at the end of the
expression can be omitted. For example, entering “25 -f (3 x (9 + 12 =”
is equivalent to “25 -r (3 x (9 + 12))
