Answer 2

Sure, I can help you with those calculations:

1. $\frac{1}{2} - (+4)$: To subtract a positive 4 from $\frac{1}{2}$, you can treat the positive 4 as $\frac{8}{2}$, since $4 = \frac{8}{2}$. Then you can perform the subtraction:

   $\frac{1}{2} - \frac{8}{2} = \frac{1 - 8}{2} = \frac{-7}{2}$

   So, $\frac{1}{2} - (+4) = -\frac{7}{2}$.

2. $-\frac{5}{11} - (-\frac{5}{11})$: When you subtract a negative value, it's equivalent to adding the positive value. So, the subtraction becomes an addition:

   $-\frac{5}{11} + \frac{5}{11} = \frac{-5 + 5}{11} = \frac{0}{11} = 0$

   Therefore, $-\frac{5}{11} - (-\frac{5}{11}) = 0$.
