Some simple calculators also include percentage, square root, and memory functions. Unlike scientific calculators, which can handle trigonometry and logarithms, the simple calculator focuses only on the most essential mathematical operations.
📖 History of the Calculator
Before the invention of the modern calculator, people used:
- Abacus (ancient tool for counting)
- Slide rule (used before electronic calculators)
- Mechanical adding machines
In the 1960s and 70s, electronic calculators became popular. Today, calculators are found everywhere: in schools, offices, computers, and smartphones.
🔎 Why Use a Simple Calculator?
People rely on simple calculators for:
- Quick math – no need to solve by hand
- Accuracy – reduces calculation errors
- Time-saving – faster than manual calculation
- Convenience – available on phones, computers, or as handheld devices
