Question 12
Study the shape rules shown. Find the value of 24 inside a circle inside a triangle. Apply nested operations from the innermost shape outwards.


Use the simple consistent shape rules illustrated by the first source diagram. The second source occurrence adds an extra square outline around the circle containing 3, while still showing 6; that outline is treated as a drawing error and is preserved in the solution for comparison.
