1. Problem Description

The problem asks us to evaluate the expression A=2023×2025+12024A = \frac{2023 \times 2025 + 1}{2024}.

2. Solution Steps

Let x=2024x = 2024. Then, we can rewrite the expression as
A=(x1)(x+1)+1xA = \frac{(x-1)(x+1) + 1}{x}.
We can expand the numerator:
(x1)(x+1)+1=x21+1=x2(x-1)(x+1) + 1 = x^2 - 1 + 1 = x^2.
Therefore,
A=x2x=xA = \frac{x^2}{x} = x.
Substituting x=2024x = 2024 back into the expression, we get A=2024A = 2024.
