  • but your generalization part is awesome.!

  • we actually can figure out that 13!+2 is divisible by 2.. reason .. 13! is even and 2 is also even.. even+even = even. hence, it is divisible by 2.

  • Amazing!

  • 153 was very very hard. Those of you working toward 700+ should worry about it. I got bowled out by this problem :( too

  • Could you further explain or provide an alternative explanation on 153 I did not follow

  • These videos are great!

    Can you explain for #153 why K had to be prime? Didn't follow the reasoning on that...
