Kaila looked at her starting depth: . She needed to reach -8 . She swam to the first seabed tunnel, which had a glowing sign: +3 . If she swam through that, she’d go up to -4. Wrong direction. The next tunnel was -2 . From -7, minus 2 is -9. Too deep. The third was +5 , which would send her to -2. Even worse.
Kaila nodded. She’d played the easy levels. She knew that to get to -8 from the surface, she had to go down 8 units. Simple. math snacks pearl diver
Second gate: (where y = 6). 6 - 4 = 2, not 10. False. She veered left, through a different archway marked TRUE . Kaila looked at her starting depth:
She was ready.
Finally, the last gate: (with no given value for x). She had to find the x that made it true herself. Kalia stopped floating. She whispered the steps: “If I subtract x from both sides, 3 = x - 1. Then add 1 to both sides… x = 4.” She swam to a glowing keypad on the seabed, typed 4 , and the final gate dissolved. If she swam through that, she’d go up to -4
