It takes him 2*49=<<2*49=98>>98 hours to go from knowing how to play to proficient
So he spends 98+2=<<98+2=100>>100 hours combined on those
So it takes him 100*100=<<100*100=10000>>10,000 hours to become a master from proficient
So the total time was 100+10000=<<100+10000=10100>>10,100 hours
#### 10,100
