130.
200/2 = 100 then + 30.
Pretty simple. Divide by half means divide in half, not divide by 0.5 etc.

Yep, poor grammar is the issue, taken literally it's obviously 430, however, it could be also divide in half and add 30 = 130 as much as it could be 32..
half of what? a marsbar?Divide 200 by half
unless it crashes a calculator then it works perfectly and I've never seen a calculator crash yetActually, assuming all numbers integers. Then 200/0.5 would give a divide by zero error and the add 30 would be left hanging. What's that? half is obviously meant to interpreted as a floating point number? Where does it say that in the question?
Yeah I agree. However 'half' on its own is not grammatically correct either. 'Half' is not a number, it should be 'one half', which is a number.Divide by half
Divide in half
They are different and will get you different answers.
The original question is BY half. If you then apply it as "in" half then you have read it wrong.

The whole thing is bobbins.
Anyway, numbers aren't even real so there is no point arguing about it. Numbers are just a manmade construct to help model and understand the universe and everything in it.
We are not really talking grammatically, we are talking about mathematically.
No, you're talking about grammar. The translation of the words into a mathematical structure is a question of grammar, and the ambiguity comes from that translation. Grammar is descriptive rather than prescriptive, and like the silliness around double negatives the fact is that the most English speakers who might say "divide by half" will have intended the same meaning as "divide by two" or "divide in half"; just as most speakers who might say "I ain't done nothing wrong!" do, in fact, mean they did nothing wrong despite the howlings of prescriptivist grammar mavens.
There is no "right" or "wrong" way to interpret this kind of "maths" problem.
