Working Backwards, Leaping Forwards
Working backwards, leaping forwards
In mathematics lessons, you might be given a question and asked to work out the answer, but these problems are a little bit different! To solve them, you'll need to think about the relationships between functions and operations and their inverses, and work backwards in order to leap forward!
What is the smallest number of answers you need to reveal in order to work out the missing headers?
Try entering different sets of numbers in the number pyramids. How does the total at the top change?
When number pyramids have a sequence on the bottom layer, some interesting patterns emerge...
Can you find the hidden factors which multiply together to produce each quadratic expression?
Can you match the charts of these functions to the charts of their integrals?
A function pyramid is a structure where each entry in the pyramid is determined by the two entries below it. Can you figure out how the pyramid is generated?
