Explanations:
1-5:
6-10:
is a system of binary & decimal no. converter –
0 – #
1 – &
10 – &#
11 – &&
100 – &##
101 – &#&
from the right side, each digit is multiplied with power of 2 (starting with 20,
21 , 22 and so on. Then all these are added to form
decimal system.
as for 5 – &#&, that means 101 -> (1×20) + (0x21) + (1×22)=
5
as,
6- 1010011 = (1x 20) +(1×21)
+(0x22) +(0x23) +(1×24) +(0x25)
+(1×26)
+ 2 + 0 + 0 + 16 + 0 + 64 = 83
