Write the temperature difference between five pair of places:
-22 C and -15
19 C and -15C
-15C and -6 etc.
is it 7 C in the first instance ignoring the minus degrees and 4 degrees in the second instance and last 9 in the last or is the first one as follows
-22 - (-15)=-37 which is in my view incorrect.
Please help!!
