1. The first sentence, "If I had a lot of money, I would buy a new laptop," expresses a hypothetical situation in which the speaker currently does not have a lot of money. The sentence suggests that if the speaker had a lot of money, they would choose to purchase a new laptop.
2. The second sentence, "As I don't have a lot of money, I don't buy a new laptop," directly states that the speaker does not have a lot of money, resulting in them not buying a new laptop. This sentence affirms the reality of the situation.
Regarding the comparison between sentences 1 and 2: They convey slightly different nuances. Sentence 1 presents a hypothetical scenario, while sentence 2 states a current fact. Therefore, they are not necessarily equivalent, but the intention of both sentences is to communicate that the speaker cannot buy a new laptop due to a lack of funds.
3. The sentence "If I had had a lot of money, I would have bought a new laptop" is an example of the third conditional, expressing a hypothetical situation in the past that did not occur. It implies that the speaker did not have a lot of money at some point in the past, and as a result, they did not buy a new laptop.
4. The statement "As I didn't have a lot of money, I didn't buy a new laptop" straightforwardly indicates that the speaker did not buy a new laptop in the past due to their lack of funds.
Regarding the comparison between sentences 3 and 4: They convey the same meaning and are equivalent in terms of expressing a lack of funds as the reason for not buying a new laptop in the past.
As for grammatical correctness, all four sentences are grammatically correct, properly using conditional statements and expressing different scenarios based on the speaker's financial situation.
