Example: Calculate (9 + 17 4) ÷ 4.
Keystrokes
9 v
Digit entry terminated.
17 +
(9 + 17).
4 -
(9 + 17 4).
4 ÷
(9 + 17 4) ÷ 4.
Even more complicated problems are solved in the same manner-using
automatic storage and retrieval of intermediate results. It is easiest to work
from the inside of parentheses outwards, just as you would with calculations
on paper.
Example: Calculate (6 + 7) × (9 3)
Keystrokes
Display
6 v
6.0000
First solve for the
intermediate result of (6 + 7).
7 +
13.0000
9 v
9.0000
Then solve for the
intermediate result of (9 3).
3 -
6.0000
*
78.0000
Then multiply the
intermediate results together
(13 and 6) for the final
answer.
Try your hand at the following problems. Each time you press v or a
function key in a calculation, the preceding number is saved for the next
operation.
(16 × 38) (13 × 11) = 465.0000
4 × (17 12) ÷ (10 5) = 4.0000
