Capitolo 1, Problema R.2.87
Evaluate each expression. See Example 5. 5 - 7 • 3 - (-2)³
Guida verificata passo dopo passo1
Identify the order of operations to evaluate the expression correctly. Remember the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
Evaluate the exponent first: calculate \((-2)^3\). This means raising -2 to the power of 3.
Next, perform the multiplication: calculate \(7 \times 3\).
Now substitute the results back into the expression and simplify the expression from left to right, handling addition and subtraction accordingly.
Combine all the terms step-by-step to get the simplified expression, ensuring you carefully handle the signs (positive and negative) during addition and subtraction.

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
Order of Operations (PEMDAS/BODMAS)
The order of operations dictates the sequence in which mathematical operations are performed: Parentheses, Exponents, Multiplication and Division (left to right), Addition and Subtraction (left to right). This ensures consistent and correct evaluation of expressions.

Exponents
Exponents represent repeated multiplication of a base number. For example, (-2)³ means multiplying -2 by itself three times: (-2) × (-2) × (-2). Understanding how to evaluate exponents, especially with negative bases, is crucial.
