Let's evaluate the expression step by step by finding the absolute values:

1. $|10| = 10$
2. $|-5| = 5$
3. $|-3| = 3$

Now substitute these values into the expression:

$|10| - |-5| + |-3| = 10 - 5 + 3$

Perform the operations:

$10 - 5 + 3 = 8$

Final Answer:

The correct option is 8.

1. What are absolute values and why are they always non-negative?
2. How does absolute value affect the signs of numbers?
3. What would the expression become if we changed $-5$ to 5?
4. Can the absolute value of a number ever be negative?
5. How do absolute values relate to distances on the number line?

Tip: Absolute values represent the distance of a number from zero on the number line, regardless of direction.
