🌍 Where You'll See This in Real Life

Change
bill ₹100, paid ₹150 → ₹50 back
You hand a ₹500 note for a ₹287 purchase. The shopkeeper does ₹500 − ₹287 = ₹213 in their head — subtraction at every till.

Time
6 hours from 5 PM = 11 AM
6 hours from 5 PM means 5 PM − 6 hr = 11 AM. Same maths runs on every alarm app and meeting reminder.

Distance left
100 km trip, 60 km done = 40 km remaining
Halfway through a 100 km drive your odometer says 60 km — remaining = 100 − 60 = 40 km. Range anxiety on EVs is pure subtraction.
