代数
a branch of mathematics in which abstract letters and symbols represent numbers in order to generalize the arithmetic
Algebra is a branch of mathematics that uses symbols and letters to represent numbers and quantities in equations and formulas. It helps solve problems involving unknown values by manipulating these symbols according to mathematical rules. Algebra is widely used in fields like science, engineering, and finance to model relationships and solve real-world problems.
