#-5#

Explanation:

There are two key phrases: 'Subtract from' and 'quotient,'

A quotient is the answer to a division.

#-90 div 9 = -10#

#-5# has to be subtracted FROM the quotient, so the quotient has to be written first.

#-10 - (-5)" "larr# the number to be subtracted is a negative.

#= -10 + 5" "larr# subtracting a negative is the same as adding

#=-5#

This process can be written as one expression with two terms:

#-90 div9 -(-5)#

#= -10+5#

#=-5#
