 The four-band resistor is built up like this:

 | ------- | ------- | ---------- | --------- |
 | Value_1 | Value_2 | Multiplier | Tolerance |
 
 Examples:
 
 - orange-orange-brown-green would be `330` ohms with a `±0.5%` tolerance.
-- orange-orange-red-grey would be `3300` ohms with `±0.05%` tolerance.
+- orange-orange-red-grey would be `3300` ohms with a `±0.05%` tolerance.
 
 The difference between a four and five-band resistor is that the five-band resistor has an extra band to indicate a more precise value.

 There are also one band resistors.
 One band resistors only have the color black with a value of 0.
 
 
 Your program should translate an input `list` of resistor band colors into a label:
 
-"... ohms ...%"
+"... ohms ±...%"
 
 So an input `list` of `["orange", "orange", "black", "green"]` should return:
 
 "33 ohms ±0.5%"
 
-When there are more than a thousand ohms, we say "kiloohms".
- That's similar to saying "kilometer" for 1000 meters, and "kilograms" for 1000 grams.

 Like the previous [`Resistor Color Duo`][resistor-color-duo-exercise] and [`Resistor Color Trio`][resistor-color-trio-exercise] exercises, you will be translating resistor color bands to human-readable labels.
 
 - Each resistor has a resistance value.
-- Resistors are small - so small in fact that if you printed the resistance value on them, it would be hard to read.
+- Resistors are small — so small in fact that if you printed the resistance value on them, it would be hard to read.
   To get around this problem, manufacturers print color-coded bands onto the resistors to denote their resistance values.
 - Each band acts as a digit of a number.
   For example, if they printed a brown band (value 1) followed by a green band (value 5), it would translate to the number 15.
