Scientific calculators compute much more complex equations and problems than basic calculators and are often used to solve statistical and trigonometric calculations. Basic calculators can compute basic math functions such as addition, subtraction, multiplication, division, exponentiation, and logarithm. Today, there are three major types of calculators: basic, scientific, and graphic. By 1985, the first graphical calculator was introduced and further advancements in the calculator industry were made. The modern electronic calculator was introduced in the 1960s, but didn’t take the world by storm until the 1970s. With the passage of time, the slide rule became the next major advancement in calculators which was then dethroned by the use of mechanical calculators. It all began with the abacus, which simplified the addition of large quantities of units. Before the invention of the modern calculator, many technologies were created to help humans count and calculate various problems. Most modern scientific and graphing calculators are more powerful than older full-sized computers. Calculators come in a range of sizes, and perform various different tasks.
