Introduction
This worksheet transforms traditional vertical subtraction into an engaging puzzle. Learners are asked to find missing digits in subtraction problems, turning each exercise into a number game that sharpens subtraction skills and logical thinking.
What Makes This a Subtraction Puzzle
Each problem is presented in a vertical format with two rows representing the minuend and the subtrahend, along with a third row for the difference.
Unlike standard subtraction problems, certain digits are missing from each row. Learners must carefully analyze the subtraction structure to determine which digits correctly complete the puzzle.
Right-to-Left Reasoning with Missing Digits
Subtraction is performed using the traditional right-to-left approach. The presence of missing digits requires learners to think backward and forward across place values while applying borrowing (regrouping) correctly.
This combination of vertical subtraction and missing information adds depth and encourages careful reasoning rather than routine calculation.
Configurable Worksheet Options
This is a configurable, online subtraction worksheet that adapts to different skill levels and learning goals.
- Choose the number of digits in the minuend and the subtrahend
- Choose to exclude the 1s or 0s from both the minuend and the subtrahend
