Answer 2

x<<n means duplicate x n times.

x>>n means n times floor division of x by 2.

Actually it is bitwise shifting but thats how to compute it.

Answer 3

KrOW Tim Thuma thank you for now... I'll read the lessons

Answer 4

>> and << are bit shift operator (if operators are integer).
>> shift bits on right while << on left. Take 12 in base 2:
12= 1100

then:

12>>2 = 11(base 2)= 3
12<<2= 110000(base 2)= 48
