AdditionsSubtraktionsoperation

Addition and subtraction are fundamental arithmetic operations that involve combining or separating quantities. Addition is the process of determining the total amount when two or more quantities are combined. It is represented by the plus sign (+). For example, the sum of 3 and 4 is 7, written as 3 + 4 = 7. Addition is commutative, meaning the order of the numbers does not affect the result (3 + 4 is the same as 4 + 3). It is also associative, allowing for the grouping of numbers without changing the sum ((3 + 4) + 5 is the same as 3 + (4 + 5)).

Subtraction, on the other hand, is the process of determining the difference between two quantities. It is represented by the minus sign (-). For example, the difference between 7 and 4 is 3, written as 7 - 4 = 3. Subtraction is not commutative; the order of the numbers affects the result (7 - 4 is not the same as 4 - 7). However, it is associative, similar to addition.

Both addition and subtraction are essential in various fields, including mathematics, science, engineering, and everyday life. They are used for counting, measuring, and calculating changes in quantities. Mastery of these operations is crucial for developing problem-solving skills and understanding more complex mathematical concepts.
