combine the 4 integers to write expressions that equal the following answers
(-3) (5) (15) (-9)
__ __ __ __= -9
__ __ __ __= 8
__ __ __ __=9
__ __ __ __=-7
combine the 4 integers in 2 other ways and solve each expression
[ (–3) x (5) ] + (15) + (–9) = –9
(–3) + (5) + (15) + (–9) = +8
[ (–3) x (5) ] + (15) – (–9) = +9
(5) + (15) – [ (–3) x (–9) ] = –7
.
