[EX Q]: Question: The meaning of Polish 'doing something on knees' or 'on a knee' is completely different than English:  s://www.macmillandictionary.com/dictionary/british/on-your-knees It is rather a metaphor to a student who instead of doing his homework properly at the home, he did it in hurry, supported his notebook on knees and did it in a short break between classes. In other words it means doing something in hurry, usually resulting in poor quality and unsophisticated enough. Some usage: Who designed this building? Looks like some architect 'made it on a knee'... Or nowadays according to software engineering: There are lots of bugs in this application! They came short on deadlines and 'wrote it on their knees' even without unit tests... My question is, is there an English equivalent (in idiom or phrase) which preserves this meaning better? Edit After reading some answers I realized that my examples were a little bit misleading. In reality, the phrase does not carry itself any negative connotations about the 'author'. Rather poor quality of his job results. The only negative connotations about author we can only deduce from the quality of his job: 'He did his job inaccurately so we can assume that he may be inaccurate.' or 'You Will Know Them by Their Fruits' sort of thing.

[EX Q]: Question: I'm referring to the peculiar habit I sometimes see in formal documents, where a number is given numerically after it's spelled out. It seems quite redundant: I need five (5) kumquats, stat! (Though it isn't always in a legal context, might it be related to this answer on this question?) 
Answer: I looked into this myself recently and couldn't find a definitive answer. The best I came up with was that numeric values in a formal document or contract are often crucial to its purpose. Restating a number in parentheses after spelling it out is a way to ensure the reader that the number is correct. It also draws the eye to the numbers, allowing for quick perusal of a document, say a purchase order. These are practical reasons; whether there is some historic reason for it I do not know.
[EX A]: no

[EX Q]: Question: In the movie Easy A, the character Todd said "See you at salt mines" to Olive when they met at Melody's party. What does salt mines mean? Does it really mean "a mine for salt"? 
Answer: Don't discount the simplest explanation: that there may actually be a place called Salt Mines, which should have been capitalized. For instance, there is a place called Salt Mines here, in Northern Ireland. It's not a salt mine any more: it's a park, which has cycling routes / jumps, with a golf course and so on nearby. In other words, it's a place where people hang out; a place where two people might very well see each other later. This is all assuming that you didn't leave out the word "the", of course. If it's "see you at the salt mines", then yes, they're probably calling the school a salt mine, as a half-joke.
[EX A]:
no
