mantissa

Does anybody know how to go out solving this problem?

* a = 1.0 × 2^9
* b = -1.0 × 2^9
* c = 1.0 × 2^1

Using the floating-point (the representation uses a 14-bit format, 5 bits for the exponent with a bias of 16, a normalized mantissa of 8 bits, and a single sign bit for the number), perform the following two calculations, paying close attention to the order of operations.

* b + (a + c) = ?
* (b + a) + c = ?

So, title says it all. Why are floating point values so prolific in computer programming.
