Calculators can perform math functions quickly and easily. The most common functions are addition (+), subtraction (-), multiplication (*) and division (/). Press the “=” sign to get the answer. Note that many calculators use different symbols for multiplication (x) and division (÷), and "C" for "Clear"—the erase function. To use the calculator,

The Simple Virtual Calculator supports the following operations: • Addition (key '+')
• Subtraction (key '-')
• Multiplication (key 'X')
• Division (key '/')

Memory Operation

The calculator has one memory that can be used for storing values temporarily. To clear the memory (set it's value to 0), press the key 'MC'. To recall the value stored in memory use the key 'MR'. To add to the value in memory, press 'M+'. To subtract a value from the memory use the key 'M-'. Turn the calculator on by pressing the "On/C" button. Turn the device off by pushing the "2ndF" button and then "Off." ON

CE.C clears the last number you entered (‘clear entry’) and turns the calculator on. AC clears all numbers entered (‘all clear’).
This is what a calculator can look like. However, every calculator is slightly different. Keys
÷ x + are called operation keys.
0. is the display (for the numbers you have entered
and the answer when you finish).
More function keys
These keys are called advanced function keys.
% is the percentage key.
+/- changes between positive and negative numbers.
MR M- M+ MC are memory keys.

Press Stat button on calculator to operate the calculator in statistics mode Off = Turns off the calculator in any functional mode
ON = Swithces on the calculator
C = cancel all input into the calculator
CE = cancel last entry into calculator

from arithmetic thorugh diﬀerential equations and was over 1,000 pages!
If we are subtracting a fraction in the problem, it may be easier to avoid a future

...Divisor | Divisibility condition | Examples |
1 | Automatic. | Any integer is divisible by 1. |
2 | The last digit is even (0, 2, 4, 6, or 8).[1][2] | 1,294: 4 is even. |
3 | Sum the digits. If the result is divisible by 3, then the original number is divisible by 3.[1][3][4] | 405 → 4 + 0 + 5 = 9 and 636 → 6 + 3 + 6 = 15 which both are clearly divisible by 3.
16,499,205,854,376 → 1+6+4+9+9+2+0+5+8+5+4+3+7+6 sums to 69 → 6 + 9 = 15 → 1 + 5 = 6, which is clearly divisible by 3. |

...Fractions are ways to represent parts of a whole. Common fractions are ½ and ¾. These are proper or regular fractions. Some fractions are called mixed numbers. These are represented by a whole number with a fraction (proper fraction). 1 ½ and 2 ¾ are good examples. An improper fraction has a larger number on the top than on the bottom, such as 9/8. I will explain how to convert these fractions to decimals. I will show you how to change an improper fraction to a mixed number. Operations...
