Answer: -202

Explanation:

Lets split this expression in neighbouring pares and calculate the value of each pair .

1-3=-2

2-4=-2

3-5=-2

4-6=-2

**************

101-103=-2

As we can notice the value of each pair is -2

The number of such pairs is 101.

So to get the total amount we have (-2)*101=-202
