36. Humans use denary OR decimal numbers in our everyday life.
Computers use Binary instead
Base 10
denary
1,2,3...
Base 2
binary

37. Converting Denary to Binary
For example to convert the number 29 write the column headings: 32 16 8 4 2 1 1 1 1 1
1 is equal to the 1 column so put a 1 in the 1 column. Add up the columns to check you have the correct answer. 29 =

38. Convert the Denary Numbers into Binary32 16 8 4 2 1
54 – 32 = 22
54 = 1 1 1 1
22 – 16 = 6
6 – 4 = 2
2 – 2 = 0 = 54 32 16 8 4 2 1
25 = 1 1 1
25 – 16 = 9
9 – 8 = 1 = 25

39. 4+1 = 5 Binary to denary conversions 1 means ‘on’ and 0 means ‘off’
128 64 32 16 8 4 2 1
= 5
4+1 = 5

42. Convert the Denary Numbers into Binary32 16 8 4 2 1
54 – 32 = 22
54 = 1 1 1 1
22 – 16 = 6
6 – 4 = 2
2 – 2 = 0 = 54 32 16 8 4 2 1
25 = 1 1 1
25 – 16 = 9
