Answer 1

To find out how many beads Niel started with, let's analyze the equation given:

\[ \frac{b}{8} + 25 = 500 \]

We can break this down step by step to identify the operations needed to solve it:

1. **Identify the operations:**
- To isolate \( \frac{b}{8} \), we subtract 25 from both sides. This is a **subtraction** operation.
- Then, to solve for \( b \), we need to multiply both sides by 8. This is a **multiplication** operation.

Thus, the correct pair of operations used in this process is **subtraction and multiplication**.

So, the answer is:

**subtraction and multiplication**.
