Parentheses Calculations
In ALG mode, you can use parentheses up to 13 levels. For example, suppose you
want to calculate:
9
1285
30
×
−
If you were to key in 30
¯
85
Ã
, the calculator would calculate the
intermediate result, 0.35. However, that’s not what you want. To delay the division
until you’ve subtracted 12 from 85, use parentheses:
