Binary counting:
Binary uses only 0's and 1's. Switches have either on or off so we can use them
for Binary counting. 
If a switch is off the number would be 0 and if it's on the number would be 1
As we have 3 switches, Switch 1 = 1, Switch 2 = 2, and Switch 3 = 4
If Switch 1 and Switch 3 are in the on position the count would be 1 + 4 which = 5
 
If there were more switches, binary counting would see it as (if turned on):
Switch 1 = 1
Switch 2 = 2
Switch 3 = 4
Switch 4 = 8
Switch 5 = 16
Switch 6 = 32
Switch 7 = 64
Switch 8 = 128
 
If all were turned on it would be 1+2+4+8+16+32+64+128 which would = 255
