“Minus times minus equals plus,
The reason for this we need not discuss.”

“A person’s life story is equal to what they have plus what they want most in the world, minus what they’re actually willing to sacrifice for it.”

“Life minus love equals zero.”

“It is possible to relegate the epoch of the starting of the expansion to minus infinity, e. g. by using instead of the ordinary time the logarithm of the time elapsed since the beginning. But this is only a mathematical trick. We call zero minus infinity, but that only means that we allow the universe an infinite time to get well started on its course of expansion, but it does not make the time during which anything really happens any longer.”

“Troy: Hi, I'm Troy McClure. You may remember me from such educational films as "Two Minus Three Equals Negative Fun" and "Firecrackers: The Silent Killer."”

“They've gotta stop reporting wind chill. That's nonsense. It really is. I don't know where they came up with it, why they came up with it, but it's a lie. They come on, "Well, it's 27 degrees today, but with the wind chill, it's minus 3." … WELL, THEN IT'S MINUS 3, ASSHOLE! I don't need to know what the weather was like if the conditions were perfect!”

“There is no reason to deny the Macedonians' own traditions about their early kings and the migration of the Macedones[.. ] The basic story as provided by Herodotus and Thucydides, minus the interpolation of the Temenid connections, undoubtedly reflects the Macedonians' own traditions about their early history.”

“Hey, you’re lucky. My cabin is closest to the stables. I can hear her yelling all night: FIRST PLACE OR DEATH! AN A MINUS IS A FAILING GRADE! Leo really needs to design a gag that’s better than my old sock.”

“Incompetence plus incompetence equals incompetence”

“It was not, however, a matter of interest to me only with respect to my divisions, since as a member of the Executive Committee, I was a kind of general executive and so had begun to think from the corporate viewpoint. The important thing was that no one knew how much was being contributed — plus or minus — by each division to the common good of the corporation. And since, therefore, no one knew, or could prove, where the efficiencies and inefficiencies lay, there was no objective basis for the allocation of new investment. This was one of the difficulties with the expansion program of that time. It was natural for the divisions to compete for investment funds, but it was irrational for the general officers of the corporation not to know where to place the money to best advantage. In the absence of objectivity it was not surprising that there was a lack of real agreement among the general officers. Furthermore, some of them had no broad outlook, and used their membership on the Executive Committee mainly to advance the interests of their respective divisions.
