"Minus times minus makes a plus" makes perfect sense.
In fact it emphasizes the fact the rule is based on the signs alone. The fact that negative numbers also have a magnitude is of no account whatsoever in regards to this sign rule. Think of the implied subjects and objects here being the signs, not the numbers. Or, don't, I don't care.

Cheers,
