I wored it out by at first guessing some of the shapes values. Iguessed at first circles could be, I guessed 3. Then in the row which equals 18. I needed to know what added up to 18. 3 + 3 + 3 + ? = 18... 9! Then I tried another column and the answer was wrong. So instead of 3, I tried 4 and then I went onto the triangles. I guessed 6, The squares, 8 and then I had to work out what the hexagons was... Hexagon + square + hexagon + square. Squares = 8 each times 2 = 16. 16 + ? = 30. 14 + 16 = 30. 14 divided by 2 = 7. 7+7+8+8=30. The hexagons equal 7!Then I had to work out this sum. Triangle+hexagon+circle+cicle
6+7+4+4=21! The answer is 21!
