HOW TO PLAY: Calculate using the numbers in the box to solve for a target number.  All four numbers must be used only once for each solution.  Add, subtract, multiply and/or divide using order of operations rules.  At least one solution is guaranteed for targets -6 to 6.

.1 1
2 5
  
(1-2) ÷ 5 ÷ .1 =-2
( 5x.1-1 ) x 2 =-1
5 x 2 - 1 ÷ .1 = 0
2 x ( 1-5x.1 ) = 1
5 x 2 x .1 + 1 = 2
( 2÷5-1 ) ÷ .1 =-6 2 ÷ 5 ÷ .1 - 1 = 3
(1-2) ÷ .1 + 5 =-5 5 x ( 1-2x.1 ) = 4
( .1x2-1 ) x 5 =-4 (2-1) ÷ .1 - 5 = 5
( 5-1÷.1 ) + 2 =-3 ( .1x2+1 ) x 5 = 6
   

It's your turn!  Use the numbers below to reach 1 to 6 and -1 to -6.

  
.6 3
6 7
