 On one page, there was a single question: **Can every number find its way to 1?**
 It was tied to something called the Collatz Conjecture, a puzzle that has baffled thinkers for decades.
 
-The instructions seemed simple.
+The rules seemed simple.
 Pick any positive integer:
 
 * If it's even, divide it by 2.
 * If it's odd, multiply it by 3 and add 1.
 
 Then, repeat these steps with the result, continuing indefinitely.

+Curious, we picked number 12 to test and started the journey:
 
 12 ➜ 6 ➜ 3 ➜ 10 ➜ 5 ➜ 16 ➜ 8 ➜ 4 ➜ 2 ➜ 1
 
 Counting from the second number (6), it took 9 steps to reach 1, and each time the rules repeated, the number kept changing.
-At first, the steps seemed unpredictable — jumping up, down, and all over — yet they always ended at 1, no matter the starting number.
+At first, the steps seemed unpredictable — jumping up, down, and all over.
+Yet the conjecture states that no matter the starting number, we'll always end at 1.
 
 It was fascinating, but also puzzling.
 Why does this always seem to work?
