$-$Calculate $(4\mathrm{.}41762275**{10}^{-3}+6\mathrm{.}34225625**{10}^{-3})$ by hand, assuming each of the values are stored in the $16-$bit half precision format described in the textbook. Assume $1$ guard, $1$ round bit, and $1$ sticky bit, and round to the nearest even. Show all the steps, and write your answer in both the $16-$bit floating point format and in decimal.
