-7+-+8+%2B+5+%2B+%28-2%29+-+6 Start with the given expression


-15+%2B+5+%2B+%28-2%29+-+6 Subtract -8 from -7 to get -15 (ie -7-8=-15 )


-15+%2B+5+-+2+-+6 Rewrite 5%2B%28-2%29 as 5-2


-15+%2B+3+-+6 Subtract 2 from 5 to get 3 (ie 5-3=2 )


-12+-+6 Add 3 to -15 to get -12 (ie -15%2B3=-12 )


-18 Subtract -6 from -12 to get -15 (ie -12+-+6=-18 )



So -7+-+8+%2B+5+%2B+%28-2%29+-+6=-18
