N.B. Each week or so, I try to document the random and not-so-random things that I’ve learned during the week.

An augend is the quantity to which another is added. For example, if you have the equation:

$$2+3=5$$

Then 2 is the augend and 3 is addend.

In the case of subtraction, the subtrahend is the quantity subtracted from the minuend. So in the following expression:

$$12-7=5$$

12 is the minuend and 7 is the subtrahend.

The word baleful means “menacing” or “threatening harm”. For example, “The monster cast a baleful glance at Beowulf.”
