The first two digits represent the two digits in the answer. The third digit represents the number of zero's you must place after the two digits. The answer will be OHMS. For example: 334 is written 33 X 104. This is written 330,000 ohms. The comma can be replaced by the letter "k". The final answer is: 330k.223 = 22 X 103 = 22,000 = 22k8202 = 82 X 103 = 82,000= 82k

There is one trick you have to remember. Resistances less than 100 ohms are written: 100, 220, 470. These are 10 and NO zero's = 10 ohms = 10R or 22 and no zero's = 22R or 47 and no zero's = 47R. Sometimes the resistor is marked: 10, 22 and 47 to prevent a mistake. 4R7 = 4.7 Ohm0 = 0 Ohm0R22 = 0.22 ohm000 = 0 Ohm Remember:

R = ohmsk = kilo ohms = 1,000 ohmsM = Meg = 1,000,000 ohmsThe 3 letters (R, k and M) are put in place of the decimal point. This way you cannot make a mistake when reading a value of resistance.
