Verify that `a -: (b+c) != (a -: b) +(a -: c)` for each of the following values of `a, b and c.` (a) `a=12,b=-4,c=2` (b) `a=(-10),b=1,c=1`

Explanation

To verify that \( a -: (b+c) \neq (a -: b) + (a -: c) \) for the given values of \( a, b, \) and \( c \), we will calculate both sides of the equation for each set of values separately.

### Part (a): \( a = 12, b = -4, c = 2 \)

1. **Calculate \( b + c \)**:
\[ b + c = -4 + 2 = -2 \]
