Things to try

Each "equation" will have a solution like "x=2" (or maybe "x=3", etc). Try to see all the different ways this answer can be hidden.

First, try to solve the equation by adding and subtracting until you get an answer like x = (value)
Then add and subtract some more until you get x - (value) = 0
Then try to get a solution like - (value) = -x
Then just add and subtract different amounts to see all the possibilities.
  Now press "New Equation" and try out some more ... !
