di-DUKT/dɪˈdʌkt/

To deduct is to take an amount from a total: deduct tax; deduct marks. Subtract is the maths twin; take off is everyday. Deduction is the noun (already in the dictionary) and also means a logical conclusion — two senses. Invigilators deduct marks for a missing number. Do not mix with deduce (reason out).
