Get Closest to a Target Value
Choose or arrange digits so a sum, weight estimate, or decimal lands as near as possible to a target — the smaller the gap, the better. Learners minimize the difference for sums, estimated weights, and card-built decimals, including placing consecutive numbers to hit a decimal sum. It blends estimation with optimization.
