0+0):(0+0

The expression you've written is \( (0 + 0) : (0 + 0) \).

Let's break it down:

1. Calculate the values inside the parentheses:

   • \(0 + 0 = 0\).
   • So, we have \(0 : 0\).

2. Now consider the expression \(0 : 0\), which is generally understood as division. However, division by zero is undefined in mathematics.

Thus, the expression \( (0 + 0) : (0 + 0) \) is undefined.
