Question

1. \\(\frac{1}{2} \cdot 12 \cdot 2 - 25 \div 5^2\\)

Explanation:

Step1: Calculate exponent and division

First, calculate \(5^2 = 25\), then \(25\div25 = 1\). Also, calculate \(\frac{1}{2}\cdot12 = 6\) (since \(\frac{1}{2}\times12 = 6\)).

Step2: Perform subtraction

Now, substitute the results into the original expression: \(6 - 1 = 5\).

Answer:

\(5\)
