This calculator will help you understand mathematical concepts behind fraction calculation, such as simplification and reduction. After reading this manual, store it in a convenient location for future reference. 2ndF SIMP ' M Operational Notes · Do not carry the calculator around in your back pocket, as it may break when you sit down. [. . . ] You will find them especially useful when combinations of calculations become complicated, or when applying the answer of previous calculation to another operations. · Press NO to clear the independent memory ("M" symbol will disappear). · After pressing R to recall a value stored in the memory, the value as displayed will be used in the calculation. Independent memory (M) O : Stores the result in the memory. R : Recalls the value stored in the memory. @; : Adds the result to the value in the memory. 30 + (3 × 5) = (3 × 5) × 4 = 20+10­5= 121+13×2= +) 21×3­16= (Total) N3*5O 30 +R= R* 4 = N 20 + 10 - 5 O 121 + 13 * 2 @; 21 * 3 - 16 @; R NO · "Highest Common Factor" is synonymous with "Greatest Common Factor", "Lowest Common Multiple" is with "Least Common Multiple". Calculating quotient and remainder ": Calculates the quotient and remainder. 23 ÷ 5 (R: Remainder) 9. 5 ÷ 4 N 23 @" 5 = 9. 5 @" 4 = ­ 32 @"­ 5 = 23`5_ 4. 6. R3. 9. 5`4_ R1. 5 15. M 45. M 60. M 25.

If numbers longer than 5 digits are entered, normal division is performed. Last answer memory (ANS) When = is pressed, the calculation result will automatically be stored in the last answer memory. : Recalls the value stored in the last answer memory. 4 ÷ 5 = 0. 8. . . (A) N 4 / 5 = 4 × (A) + 60 ÷ (A) = 4 *@?+ 60 / @?= FRACTION CALCULATIONS Entering Fractions · To enter fractions, use the following keys: Ø : Places the symbol "/" between the numerator and the denominator. : Separates the integer (whole number) part from the fractional part of a mixed number. 0. 8 78. 2 2 4­ = 3 1 4­ = 2 * N2Ø3= 41Ø2= 2/3 4¬1/2 ¬ Enter a common denominator for the two fractions. If the entered value is not a common denominator, the cursor will be set under the value. Press d to clear the value, then enter a correct common denominator. Press N to return to the "DENOM. ?" display. · Up to 10 key strokes, including "¬" and "/", can be used to enter a fraction. Calculating with Fractions Fractions can be incorporated into an arithmetic calculation. The "SIMP" symbol will appear with a calculation result if the answer can be further simplified. Refer to the following section of this manual for details. 1+1= ­­ 23 2×­= ­1 53 N1Ø2+1Ø3= 2Ø5*1Ø3= Now that you have learned how to reduce a fraction to its lowest denominator, you can start using your calculator to perform fraction calculations quickly and efficiently. 1­ ­+1= 34 N1Ø3+1Ø4 1/3+1/4_ ªDENOM. ?SIMP 28/48 =* 12_ SIMP 28/48 = 4/12+3/12_ = 7/12 5/6 2/15 * If = is pressed instead of a number entry, the lowest common denominator will automatically be displayed. How to Simplify a Fraction Reducing to its simplest form If the result of pressing = is displayed with the "SIMP" symbol, the calculation can be reduced further. Use the ª key to set the factor of the fraction to simplify, either automatically or manually.
