Evaluate each expression. See Example 5. 12 + 3 • 4

Guida verificata passo dopo passo
1
Identify the mathematical operations in the expression: addition and multiplication in the expression \(12 + 3 \cdot 4\).
Recall the order of operations (PEMDAS/BODMAS), which states that multiplication should be performed before addition.
First, calculate the multiplication part: multiply 3 by 4, which is represented as \(3 \cdot 4\).
Next, add the result of the multiplication to 12, which is represented as \(12 + (3 \cdot 4)\).
Write the final expression after substitution and simplify step-by-step to get the evaluated result.

Concetti chiave

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.

Order of Operations

The order of operations is a set of rules that determines the sequence in which mathematical operations are performed. Multiplication and division are done before addition and subtraction. This ensures consistent and correct evaluation of expressions like 12 + 3 • 4.
