A function pyramid is built up layer by layer — enter the values for the bottom layer, and each value higher up the pyramid is determined by applying some function to the two values immediately below it.

This activity challenges you to experiment with various values and try and determine the particular function being applied.

Function Pyramids
Can you crack the code and find the function?
Select a function using the buttons at the bottom, and try and work out the function by entering various values in the bottom cells. (The higher numbers are harder.) Use the button to enter your own function and challenge a friend!
