Storm:
Isn't "Math" the plural of "Math" while Mathematics is both singular and plural as well?
I remember seeing "maths" used when I lived in England but I never understood it. It was one of the few mysterious differences that never quite penetrated for me, I guess.
Well, "mathematics" is generally treated as singular (in spite of looking plural in its spelling) in the United States (which is also treated as singular here in the U.S.A.), isn't it? "Mathematics IS my area of expertise," for example. (Likewise "The United States IS my home country.")
Therefore, I'd venture that either abbreviated form ("math" or "maths") should be considered singular as well--assuming the full term is treated as such.
I also was aware of "standing in the corner" as an alternative--rather than an adjunct--to some other form of punishment during my childhood, although I don't recall experiencing it personally. IIRC it was employed occasionally by teachers in my elementary school; paddling (by the vice-principal) was also used but quite rarely and paddlings were carried out in the hallway.
However, the embarrassment of cornertime, especially with 'southern exposure' (before and/or after a chastisement), is such an ideal complement to being spanked on one's bare behind, notably in front of opposite-gender witnesses, that it's a basic staple of spanking-oriented literature.
As it well should be (IMHO)... --C.K.
