Answer:
-1°C is the temperature on Wednesday
What is colder, -5 or -6 degrees?
A simple way to work this out.
If it is a positive number, then the higher the number the higher the temperature.
e.g 1, 2, 3, 4, 5, 6, 7
In this sequence the number to the right is higher than it’s previous numbers and the number to the left is lower than the numbers in front of it.
If it is a negative number then the higher the number after the -ve sign the lower the temperature.
eg. -7, -6, -5, -4, -3, -2, -1
In this sequence the number to the right is lower than it’s previous numbers and the number to the left is higher than the numbers in front of it.
This can be so confusing to some people.
So much so that a scratchcard game based on temperatures was withdrawn from sale as players didn’t understand the principle behind negative temperatures and got them mixed up.
