Troxler 3440-L - Subtraction; Division; Multiplication; Chain Calculations

Model 3440-L 5–25
5. 3440 OPERATIONS
SUBTRACTION
To subtract 65 from 78: press 〈7〉, 〈8〉, 〈–〉, 〈6〉, 〈5〉, then 〈=〉. The displayed
answer will be 13.
DIVISION
To divide 39 by 3: press 〈3〉, 〈9〉, 〈÷〉, 〈3〉. Press 〈=〉 for the displayed
answer of 13.
MULTIPLICATION
To multiply 33 by 3: press 〈3〉, 〈3〉, 〈×〉, 〈3〉. Press 〈=〉 for the displayed
answer of 99.
CHAIN CALCULATIONS
To perform a simple chain calculation, press 〈=〉 after each operation to get
an intermediate result. For example, to perform the calculation 2 + 5
× 9 –
3 and divide the result by 5: press 〈2〉 〈+〉 〈5〉. Then press 〈=〉 to get the
intermediate result of 7. on the last line of the display. Press 〈×〉 〈9〉 〈=〉.
The figure following the equal sign will be 63. Next, press 〈–〉 〈3〉 〈=〉 for a
result of 60. To divide this result by 5: press 〈÷〉 〈5〉 〈=〉 for the final
answer of 12.
A chain calculation such as 3+4(6+9)/2-8 must be performed using
algebraic notation: Parenthetical equations must be performed first,
followed by multiplication and division operations; then by addition and
subtraction. Therefore, the correct way to begin this calculation is: 〈6〉 〈+〉
〈9〉 〈=〉 to get the intermediate result of 15.
Next, do the multiplication 〈×〉 〈4〉 〈=〉 to get the next result of 60.
The next step is division: entering 〈÷〉 〈2〉 〈=〉 brings the next result of 30.
Finally, addition and subtraction: press 〈+〉 〈3〉 〈=〉 and 〈–〉 〈8〉 〈=〉 for the
final answer of 25.
MEMORY STORAGE ARITHMETIC
Calculator mode also includes the MS (memory storage) and MR (memory
recall) functions.
The MS function allows data to be stored in general memory for use with
other calculations or data may be stored under a specific project and station
number.
