The scientific calculator
While we might have started out using our fingers and toes to count, humanity has been busy designing machines to help with calculations for hundreds of years. From early counting devices to modern calculators, a lot has happened in between.
Today, students and professionals alike are equipped with scientific calculators capable of executing complex mathematical functions and solving equations. They save a huge amount of time compared with writing out and solving individual problems and equations.
But how did inventors move from the very first abacus thousands of years ago to the modern scientific calculator?
What is a scientific calculator?
Scientific calculators, also known as digital calculators, are electronically powered devices that can solve many different calculations used in mathematics, science and engineering.
More basic calculators typically have four core functions: adding, subtracting, multiplying and dividing. Some advanced electronic calculators include other functions like instant percentage calculators.
