A left shift 1 place is the same as multiplying by 2
A left shift 2 place is the same as multiplying by 4
A left shift 3 place is the same as multiplying by 8
In general shifting N places left is the same as multiplying by 2 to the power N (written as 2N)
NOTE: A left shift 0 places is the same as multiplying by 20 and since 20 is equivalent to 1 it is the same as multiplying by 1
