The Celsius temperature scale (as does the Fahrenheit and Kelvin scale) works on the principle that the higher the number the warmer the temperature.So you need to order these numbers in descending order if you want the warmest first. If you remember that a positive number is always larger than a negative number then you will see that the order of your example will be:18 degrees C, 4 degrees C, 0 degrees C, -1 degrees C, -11 degrees C, -18 degrees C.
14° F is 18 Fahrenheit degrees colder than freezing. 14° C is 14 Celsius degrees warmer than freezing.

one is negative and one is positive
It is: 18+16+14 = 48
-10 C = 32 + -10 x 9/5 = 32 - 18 = 14 F greater than 10 F
18 C is warmer than 15 C.
