So i usually never ask for help on my homework but i'm stumped on this one! I really would like help. Here it is: The object of this puzzle is the use the numbers 1,2,3 and 4 to express the numbers from 0-20. You can use addition,subtraction,multiplication,division, square roots or anything. You cannot repeat numbers and you must use all 4 numbers in your expression. Now i only need to get it to total 8,16,17,18,19 and 20. Thanks!

Well I can give you 17, 18, 19, and 20.... [(4+1)x3]+2=17 (4+2)x3x1=18 [(4+2)x3]+1=19 [(3x1)+2]x4=20 By the way... what grade are you in and what kind of math is this for?
