Problem 17 (Bus Route Solution): 37 students
Step 1 (Students leaving): 46 − 18 = 28. Step 2 (Students boarding): 28 + 9 = 37. (Alternatively: 46 − 18 + 9 = 37).
⚠️ Diagnostic Flags & Common Student Misconceptions
Reversal Error in Subtraction (#10, #14): Students often subtract the smaller digit from the larger digit regardless of top/bottom position (e.g., in 73 − 38, calculating 8 − 3 = 5 and 7 − 3 = 4 to get 45 instead of regrouping to get 35).
Forgetting to Decrement After Regrouping (#16): In 90 − 54, students borrow 1 ten to make 10 ones (10 − 4 = 6), but forget to reduce the 9 tens to 8 tens, resulting in 46 rather than the correct 36.
