Adding and subtracting are two of the most basic operations in mathematics. They are used to solve equations, calculate totals, and perform other mathematical tasks. The term for these operations is MATH, which is a four-letter word. Adding and subtracting are both forms of arithmetic, which is the branch of mathematics that deals with numbers and calculations. Adding involves combining two or more numbers to get a total, while subtracting involves taking away one number from another. Both operations are essential for solving mathematical problems.
