Example: Calculate (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)
First solve for the
intermediate result of (6 + 7).
Then solve for the
intermediate result of (9 3).
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
