•  2
X: I didn't buy that house?

Y: If I were you, I would buy the house

or

Y: If I were you, I would have bought the house

X: Is my calculation correct?

Y: If you included temperature in the calculation, it would be correct.

or

Y: If you had included temperature in the calculation, it would be correct.

Can you please explain when to use Type 2 or 3? I understand that type 2 me is unreal in present and type 3 is unreal in past but which one to use when contexts are given?

If I were you, I would buy the house. If I were you (but I'm not, of course), I would buy the house (that's what I would do if I were in your situation now).

If I were you, I would have bought the house. If I were you (but I'm not, of course), I would have bougth the house (that's what I would have done if I had been in your situation, a past situation).

Is it correct, Mr. Brown? ---- If you included the temperature t0 in the calculation (I don't know if you actually did), then it is correct, provided you didn't make any mistakes. If you didn't include the temperature (I don't know if you actually didn't), then the result is definitely wrong.

Is it correct, Mr. Brown? ---- If you had included the temperature t0 in the calculation (you didn't include it!), the result would have been correct. Sorry, next time remember to take account of the temperature.

I tried to give you my opinion, now let's see if others feel like commenting.
Students: Are you brave enough to let our tutors analyse your pronunciation?
Kooyeen, actually I prefer your sentence which combines both present and past tenses.With your sentence, I can imagine the answer is right in front of me and I do not know whether the student included temperature in his calculation.

If you didn't include the temperature, then the result is definitely wrong.

The reason I chose 'didn't ... would' was that I was following Type 2 format and it sounds unnatural to me.

If you didn't include the temperature, then the result definitely would be wrong.
