Answers
a type of mathematics in which letters and symbols are used to represent numbers
Answer:
Algebra is a branch of mathematics that substitutes letters for numbers. Algebra is about finding the unknown or putting real-life variables into equations and then solving them. Algebra can include real and complex numbers, matrices, and vectors. An algebraic equation represents a scale where what is done on one side of the scale is also done to the other and numbers act as constants.
The important branch of mathematics dates back centuries, to the Middle East.
History
Algebra was invented by Abu Ja'far Muhammad ibn Musa al-Khwarizmi, a mathematician, astronomer, and geographer, who was born about 780 in Baghdad. Al-Khwarizmi's treatise on algebra, al-Kitab al-mukhtasar fi hisab al-jabr waʾl-muqabala (“The Compendious Book on Calculation by Completion and Balancing”), which was published about 830, included elements of Greek, Hebrew, and Hindu works that were derived from Babylonian mathematics more than 2000 years earlier.
The term al-jabr in the title led to the word "algebra" when the work was translated into Latin several centuries later. Although it sets forth the basic rules of algebra, the treatise had a practical objective: to teach, as al-Khwarizmi put it
