Click to expand... Was this the exact text of the exercise? (It's very poorly written and open to interpretation, is why I ask.) Thank you. Eliz.

For 19, try these: 2*(8+(6/4)) (8+(6/4))*2 (6+(4*8))/2 ((8*4)+6)/2 2*((6/4)+8) (6+(8*4))/2 ((6/4)+8)*2 ((4*8)+6)/2 For 25, try these: 4*(6+(2/8)) 4*((2/8)+6) (6+(2/8))*4 ((2/8)+6)*4 If there are other rules contained in the actual problem statement, let's hear them.
