Functions & Their Definitions:
1. Addition ( + )
Definition: Adds two or more numbers together.
Formula: a + b = sum
Example: 5 + 3 = 8
2. Subtraction ( – )
Definition: Finds the difference between two numbers.
Formula: a – b = difference
Example: 9 – 4 = 5
3. Multiplication ( * )
Definition: Finds the product of two numbers.
Formula: a * b = product
Example: 6 * 3 = 18
4. Division ( / )
Definition: Splits a number into equal parts.
Formula: a / b = quotient
Example: 12 / 4 = 3
5. Percentage ( % )
Definition: Converts a number into a percentage of 100.
Formula: (a% of b) = (a / 100) * b
Example: 25% of 200 = (25 / 100) * 200 = 50
6. Square Root ( √ )
Definition: Finds the number that, when multiplied by itself, gives the original number.
Formula: √a = x (where x * x = a)
Example: √16 = 4
7. Backspace ( ⌫ )
Definition: Removes the last entered digit or operator from the display.
Example:
If the current input is “1253”, pressing Back will remove the last digit, leaving “125”.
