Here are the essential concepts you must grasp in order to answer the question correctly.
Multiplication
Multiplication is a fundamental arithmetic operation that represents the repeated addition of a number. In the expression 4 x (-2), it indicates that -2 is added to itself four times, resulting in -8. Understanding multiplication is essential for evaluating expressions that involve both positive and negative numbers.

Addition
Addition is another basic arithmetic operation that combines two or more numbers to produce a sum. In the expression 6 + (-8), the addition of a positive number and a negative number requires understanding how to navigate the number line, ultimately leading to a result of -2. Mastery of addition is crucial for solving equations and expressions.

Order of Operations
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 vital for correctly evaluating expressions like 4 x (-2) + 6, where multiplication must be performed before addition.
