To solve this problem using the equation b/8 + 25 = 500, we need to perform addition and division.

Step 1: Start with the equation b/8 + 25 = 500.

Step 2: Subtract 25 from both sides of the equation to isolate b/8.
b/8 = 500 - 25
b/8 = 475

Step 3: To solve for b, multiply both sides of the equation by 8.
(b/8) * 8 = 475 * 8
b = 3800

Therefore, Niel started with 3800 beads.

The operations needed to solve this problem using the equation "b/8 + 25 = 500" are addition and multiplication.
