IPA: //mɪˈnuːɛnd//
KK: /mɪˈnuːɛnd/
The number that you take away from when doing subtraction. For example, in the subtraction 50 - 16 = 34, 50 is the minuend.
In the equation 70 - 25 = 45, the minuend is 70.
Minuend is derived from the Latin word 'minuendus', which comes from 'minuere' (meaning to lessen or diminish) and the suffix '-endus' (indicating something that must be done). The term refers to a quantity that is to be diminished or subtracted in a mathematical operation.
Think of 'lessening' ('minuere') something that 'must be done' ('-endus') — that's why a minuend is the number you subtract from.
