Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Subtraction of Integers
Subtraction of integers involves finding the difference between two numbers. When subtracting a negative number, it is equivalent to adding its positive counterpart. For example, in the expression 8 - (-13), the operation transforms into 8 + 13, illustrating how subtracting a negative number increases the value.
Negative numbers are values less than zero, represented with a minus sign. They are essential in understanding operations involving integers, particularly in subtraction and addition. In the context of the question, -(-13) indicates the negation of a negative number, which results in a positive value, thus affecting the overall calculation.
The order of operations is a set of rules that dictates the sequence in which mathematical operations should be performed to ensure consistent results. Commonly remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction), it is crucial to follow this order when evaluating expressions to avoid errors, especially when multiple operations are involved.
