The temps that we know are colder than -5deg C 

first anything below or less than -5degC will be colder in temperature because it has a lower or smaller value, so it is colder overall. 

3 examples would be x<-5deg C

x= -6deg C
x= -7deg C
x= -8deg C

so plugging in x value we get -6<-5   -7<-5    -8<-5

If you are needing anything else please just ask! Thank you!
