- 164 (128 + 32 + 2 + 1[pic 16]
164-128=36 36-32=4 4-2=2 2-1=1
128 64 32 16 8 4 2 1[pic 17][pic 18][pic 19][pic 20][pic 21][pic 22][pic 23][pic 24]
- 255 (128 + 64 + 32 + 16 + 8 + 4 + 2 + 1) = 11111111[pic 25]
255-128=127 127-64=63 63-32=31 31-16=15 15-8=7 7-4=3 3-2=1 1-1=0

2. Express the binary numbers below in the decimal number system.
- 111 8[pic 34]
22 21 20[pic 35] [pic 36][pic 37] 1 1 1 |
22 + 21 +20 = 4+2+0 = 8
- 1011 10[pic 38]
23 22 21 20[pic 39][pic 40][pic 41][pic 42] 1 0 1 1 |
23 + 21 + 20 = 8 + 2 = 10
- 1000 8[pic 43]
23 22 21 20[pic 44][pic 45][pic 46][pic 47] 1 0 0 0 |
23 = 8
