Question

12 × 2² - 18.4 + 0.6

Explanation:

Step1: Calculate the exponentiation

First, we calculate \(2^2\) which is \(4\).
So the expression becomes \(12\times4 - 18.4 + 0.6\).

Step2: Perform the multiplication

Calculate \(12\times4\) which equals \(48\).
Now the expression is \(48 - 18.4 + 0.6\).

Step3: Perform the subtraction and addition

First, subtract \(18.4\) from \(48\): \(48 - 18.4 = 29.6\).
Then add \(0.6\) to \(29.6\): \(29.6 + 0.6 = 30.2\).

Answer:

\(30.2\)
