The document contains 7 multi-part math word problems involving topics like:
- Completing tables and graphs from functions
- Finding values from graphs and equations
- Drawing diagrams and calculating areas from transformations
- Solving simultaneous linear equations using matrices and algebra
The problems progress from completing tables and graphs to applying transformations, inverses, and solving simultaneous equations. Diagrams, tables, and algebraic steps are required to solve the various parts of each multi-step problem.
