32-40=32+(-40)=-8 (8º below zero)
32+(-40)=l-40l-l32l=40-32=8, now use the sign of the number with the greater absolute value which is -40
the answer is -8 again
when you add a positive and a negative number you subtract their absolute values and use the sign of the number with the greater absolute value, or, the sign of the number farthest away from zero
