Puzzle 3: Math Grid
In this puzzle you will be given a link to an image of a blank 3x3 grid where 9 numbers will be placed. When placed in the open spots each column and row form a math equation using plus and minus signs. At the end of each row and column will be a number which is the result of the equation. Now the equations will run in BOTH directions. So for example, for a row there will be a number answer on the left side of the grid and one on the right side of the grid. The number which is the answer to the equation is located at the end of the equation. So for the number on the left of the grid it is the answer if the equation went from right to left in that order. The number on the right of the grid is the answer if the equation went from left to right. It works the same for columns going from top to bottom or bottom to top.
Once you place the numbers and all equations are true your time will stop.
