Resistor Tolerances

Let's face it, math is hard. Anyone can figure out 5% of 100K in their head, but what about 6.8K? I hate to stop in the middle of a repair to figure if a resistor is still within it's tolerance rating and calculators only clutter up your bench. Print this chart of common resistor values, slap it up on the wall and you'll never need to stop and count on your fingers again.
