#-36.9#

Explanation:

What you are actually doing is adding 2 negative numbers together.
#(-32.4) + (-4.5)#

This means go down the number line and then further down the number line....

=#-36.9#

Or you can remove the brackets to get

#-32.4 -4.5" "larr# pos x neg = neg

#= -36.9#

This can also be compared to owing #$32.40# and then borrowing another amount of #$4.50#, so that the total debt is now #$36.90#

Your account details will be #(-32.4) + (-4.5) = -36.9#
