Positive values only. Full access to the double number line model and step navigation. The final answer is never revealed on the model.
Mild
All four operations, including negatives. Full visual support with step navigation, but still no final answer reveal on the model.
Medium
Same question types as Mild, but the visual is stripped back. No grey helper values, no extra minor ticks, and no multiply or divide loop cues.
Spicy
Same equation types as Medium, but there is no visual model. Just the question and your answer.
Very Hot
No visual. Larger values, some halves in addition and subtraction, and multiplication and division stretching beyond the 12 times tables while keeping whole-number answers.
