2 + (-1, 2) - 3,6

To simplify the expression \(2 + (-1, 2) - 3.6\), let's break it down step by step.

First, clarify that you're using the notation correctly with the tuple \((-1, 2)\). If you mean to treat \((-1, 2)\) as a vector or point, the operation will depend on the context. Here’s how it could be interpreted:

1. Assuming \(2\) is a scalar and \((-1, 2)\) is a vector: \[ 2 + (-1, 2) - 3.6 \] This makes sense if you're performing vector addition and subtraction. However, the scalar can only directly combine with another scalar.

2. If we treat \(2\) and \(-3.6\) as scalars: \[ 2 - 3.6 = -1.6 \] Now combining this with the vector \((-1, 2)\): \[ (-1.6) + (-1, 2) = (-1.6 - 1, 2) = (-2.6, 2) \]

So, combining these steps, the final result could be interpreted as the vector \((-2.6, 2)\). If all components were scalars and there's no vector operation intended, please clarify how to handle the components accordingly.
