# What is algebra?

If you had a math in junior high school, then algebra appeared in the timetable for high school lessons. What is algebra? Mathematics is divided into sections, one of the main sections is called algebra. This branch of mathematics studies operations with numbers, vectors, functions, and other objects.

Even before the sixteenth century, algebra was stated verbally. Gradually, mathematical signs appeared. Francois Vietet, a French mathematician, with his contemporaries began to use letters to denote any numbers, before that only unknown numbers were designated by letters. But these designations were not yet similar to modern ones.

Over time, algebra as a science developed and already for mathematical operations began to use the signs "plus", "minus", as well as multiplication and division. Modern algebra is started to be taught at school, and in higher educational institutions they continue to study its sections.
