Don't you feel so much easier in math class to solve any problems with a calculator? It's not just useful for classes, it made everyone's life so much easier. Calculator is one of the most important inventions in the world, you can use the calculator to solve any mathematical problems. The man who made the first calculator was called Blaise Pascal, he made the calculationg machine to help his father's work as a tax official. That calculator could only solve additions or subtractions. So later on, people made a developed calculator which could solve additions, subtractions and even mutilications and divisions. Nowadays, the basic calculator can solve additions, subtractions, division and multiplications and even roots, some of the professional calculators have lots of different programs, savings and it can be connected to the computers, too.
This invention was very important to everyone because we didn't have to solve the mathematical problems with our hands and brains. Like Pascal's father's job (tax official), it took him forever to solve the adding problems while he was working. Now, calculators are used in anywhere such as markets, any kinf of jobs and even in SCHOOL! This invention changed our lifes by helping us solve the problem easily and quickly.
