1（2）=3-2253

It looks like you're presenting an equation or algebraic expression. However, the notation is a bit unclear.

If you meant to express an equation, it could look something like this:

1 × (2) = 3 - 2253

Simplifying this would result in:

2 = 3 - 2253 2 = -2250

If this is not what you intended, please clarify your question. Are you looking for a solution to an equation, or is there a specific topic you need help with?
