Hold the resistor so the gold or silver tolerance band is on the right. Read left to right. The first two bands are digits, the third is the multiplier, and the fourth (right-most) is tolerance.
A brown-black-red-gold resistor reads as 1, 0, ×100, ±5% = 1 kΩ ±5%. Standard E12 values are 1.0, 1.2, 1.5, 1.8, 2.2, 2.7, 3.3, 3.9, 4.7, 5.6, 6.8, 8.2 — and their multiples by powers of 10.
