This lesson is optimized for mobile-first learning. Touch targets are 48px minimum. Animations use 700ms for removal (slower than addition's 500ms) to let children observe what's "going away."
Subtraction uses rose/red tones (--subtract: #E11D48) to differentiate from addition's green theme. This color coding helps children recognize operation types at a glance.
English and Hindi dialogue maintains story continuity. Riya speaks English while Arjun reinforces concepts in Hindi. Voice synthesis uses appropriate language detection.
Symbols appear AFTER physical manipulation. Children experience "taking away" through tapping before seeing − and = symbols, building concrete understanding before abstract notation.
The practice zone tracks correct/total attempts. Quiz provides empathetic explanations for wrong answers. Certificate celebrates completion regardless of score.
