I recall that the phrase "Hit-and-Trial" means "Trial And Error", that is to guess a solution and see if it is valid or not.
I've only a vague memory of reading it in some chemistry book where it was a method for balancing chemical equations. I also found this phrase in a question title on Math.SE :
The user seems to be English. When I search this phrase on Google I get "Trial and error" related links.
The problem is that I could not find any authoritative reference which mentions the meaning of "Hit-and-Trial". So please tell me if it means "Trial And Error" or not.
