Emek, Luna, and Pixel discovered a treasure map with checkpoints marked by numbers made from tens and ones. The first checkpoint showed 7 tens and 2 ones, which made 72. The next checkpoint showed 4 tens and 8 ones, which made 48. They carefully built each number and matched it to the correct place on the map. Reading the checkpoints correctly helped the team follow the trail and find the hidden treasure safely.
