binary to decimal:-

we have any binary number so we have to find that decimal number without in binary o to till that number so we lets start…

we have 101010 binary number so

first

1=1

10=2

101=5

1010=10

10101=21

101010=42

where we add 1 there we do that decimal number double and 1 add then we want add 0 so that decimal number we have to double then we want to add 1 so that decimal do double and add 1 so same way it will come .
