Addition of Integers
Addition of integers involves combining two or more whole numbers to find their total. When adding a negative integer, such as -13, it is equivalent to subtracting its absolute value from the other number. In this case, -6 + (-13) can be thought of as -6 - 13.
Negative numbers are values less than zero, represented with a minus sign. They are used to indicate a deficit or a loss in various contexts, such as financial situations or temperature scales. Understanding how to work with negative numbers is crucial for performing operations like addition and subtraction correctly.
The properties of addition, including the associative and commutative properties, help simplify calculations. The commutative property states that the order of addition does not affect the sum, while the associative property allows grouping of numbers in any way. These properties can be useful when rearranging terms to make calculations easier.
