We think the square=8 and the triangle=6 and the circle=4 and the hexagon=7.

Method 8 worked because all the cells added up to 96 so you know that the rows added up to 96 so that means that the columns add up to 96.

Meathod 6 worked because the square=8 and the triangle=6 and 8+8+6+6=28 and also 8+6=14 and the fourth columm square+triangle+2o=22 is right because the square=8 and the circle=4 and the triangle=6 and when you add them it=22 and 20s=8 like it says so it is right.

Mehtod 7 worked because all of the ways they tried to add worked.
