The expression can be rewritten as:

1/2 - 1/4 + 1/8 + 2023

To simplify the fractions, we need to find a common denominator, which is 8:

4/8 - 2/8 + 1/8 + 2023

Now we can add the fractions:

3/8 + 2023

To add a fraction and a whole number, we need to convert the whole number to a fraction with the same denominator:

3/8 + 2023/8

Now we can add the fractions:

(3 + 2023)/8

Simplifying the numerator:

2026/8

Reducing the fraction:

253 1/4

Therefore, the expression simplifies to 253 1/4.
