This is a game similiar to our 'pennies' that we use in class for subtracting integers. Might take a time or two to get used to the game, but it is very similiar.
First, drag the correct positive or negative chips to the playing circle. (then click continue)
Next, drag the correct number of pos/neg combo chips to the playing circle. (click continue again)
Then, drag the positive or negative chips, depending on the problem, to the 'trash'. (click continue)
Finally, enter your answer into the blank and check!
