This grammar sets up a pretend world. Then, you share your thoughts about that pretend world. You give your idea or ask a question about it. It is not about what really happens next.

Both 〜としたら and 〜とすれば mean "if" or "supposing". But 〜としたら is more for talking. It is for ideas that might not be true. 〜とすれば is more formal. It is for facts or strong reasons.

Don't use this when you tell someone what to do. For example, you cannot say "If it rains, take an umbrella."
