FutureStarrA Scientific Calculator With Fraction Button
Sure, you may trust that your 8-year-old has a better grasp on fractions than your new boss, but what if your new boss also has a pocket scientific calculator with a fraction button?
Calculators that display fractions sometimes have a special mode, called Math mode, that you must first select before you can enter fractions. When the calculator is in Math mode, the word "math" appears at the top of the screen. Once you have selected this mode (if necessary), look for a button with two boxes, one black and one white, arranged on top of each other with a horizontal line between them. This is the fraction button. On some models, the button may show x/y or a b/c. Pressing this button enables the fraction feature.
’ appears at the top left-hand corner of the calculator display to remind you that the button has been pressed. It disappears when you press another key. Some keys also have a third function, printed above the key in red. These functions allow numerical values stored in the calculator memories to be used within calculations and are accessed by pressing thebutton in the left-hand column of the function key area of the calculator keypad. This displays a fraction ‘template’ on the display – as shown in Figure 8 below – that contains boxes that need to be ‘filled in’. When the button is first pressed, the cursor is located in the top box ready for you to enter the numerator. To move to the bottom box to enter the denominator, use the cursor down key.4. You can calculate the value of a fraction that does not have 1 in the numerator using the division button. Specifically, the formula can be done by entering your numerator value, pressing the division key, and then inputting the denominator value. When you press the equal (=) button, you'll get your fraction value. (Source: www.businessinsider.com)
