Balance when Adding and Subtracting
Algebra is great fun - you get to solve puzzles!
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 ... ! |
