**How Calculators Work**

**Basic Operations**

**How to Perform Simple Arithmetic Operations: **Calculators accept keyboard data, process it using math rules embedded into the chips, and display the output. Simple add, subtract, multiply, and divide methods are enough. When you add two numbers, the calculator records the first, waits for the second, adds them, and displays the result.

**Example Calculations:**

**Addition (e.g., 12 + 7):** the calculator stores '12', waits for the '+' sign, and then stores '7'. The 19 number is shown when you press the '=' key.

**Subtraction (e.g., 15 - 5):** It stores "15" in memory, waits for "-," then "5," and finally, on "=," subtracts five from 15 to show "10."

**Multiplication (e.g., 4 x 6):** the calculator will remember "4", find "x," place "6," and multiply the two to show "24" on "=."

**Division (e.g., 20 / 4):** it will hold "20," wait for the "/" symbol, store "4", and then divide "20" by "4" to show "5" on "=."

**More Complex Calculations**

**Scientific, graphing, and financial calculators handle complex formulas:** Scientific, graphing, and financial calculators solve equations, plot variables, and calculate formulas. These calculators can handle variables, many calculations, and a lot of data points for statistics and charting. More complex algorithms and data structures.

**Scientific Calculators:** use series expansions and repetitive methods to calculate functions such as sine, cosine, logarithms, and exponentials.

**Graphing Calculators:** stores, then graphically shows the y-value for each incremental x-value over a given range. These devices do calculations and plot graphs.

**Memory and Programming in Advanced Calculators: **contain memory functions to save numbers or finish math. They also allow programming so users can develop functions or automate tasks. A graphing calculator can repeat a math problem with different inputs in a brief program. You can tell a scientific calculator to operate on data in a more extended program.
