i need some help working ou the values of resistors by thier coloured bands.

this is the info i have


the first two colour bands represent the numbers in the value, and the third band represents the multiplyer, or numberof zero's to add after the numbers. the codeis

black 1
brown 2
red 3
orange 4
yellow 5
green 6
blue 7
violet 8
grey 9
white 0

so a [brown-black-red] resistor is 1 k,
a [yellow-violet-orange] resistor is 47k,
a [red-red-green] resistor is 2.2m
and so on


but when i work out the values that are given as examples the answers dont match


do i


1. times the brown and black then times the answer by red
2. add the brown and black then times the answer by red



this is confusing

the reason you're getting it wrong is because you got the codes wrong!!! black is 0
