SUM / DATE

Each day, the date breaks into four numbers — some whole, some split into digits (26 → 2, 6) or factors (20 → 4 × 5). Put a sign in each gap so they make 10. The numbers stay where they land.

Tap a gap, then a sign — or drag a sign onto a gap. For parentheses, tap ( ), then the first and last number to group. Tap the same pair again to remove it.

Each level has its own four numbers. Fractions and negatives along the way are fine. A new puzzle arrives at 6 AM Pacific.
