Solve a Table or Graph Step by Step from Clues
When a table or graph has several blanks linked by clues (a total, a ratio, a difference), solve the entries you can pin down first, then use them to unlock the rest in sequence. Learners fill missing data from conditions, complete graphs from clues, and chain knowns to unknowns. It is constraint-propagation applied to data displays.
