How to solve a number pyramid

Fill every brick so each one equals the sum of the two bricks directly beneath it, working up to the single brick on top.

The method

1Add upward where you can. When two side-by-side bricks are both filled, the brick resting on them is just their sum.
2Subtract downward where you can. If a brick and one of the two beneath it are known, the other one below is the brick minus the known neighbour.
3Chase the forced bricks. Each number you fill unlocks its neighbours. Keep alternating add-up and subtract-down until the pyramid is full.
4Check the top. The apex equals the sum of the whole bottom row by its weights, so a correct bottom row always lands on the printed top number.

The one rule: Every brick is the sum of the two directly below it.
What the answer page shows: The fully completed pyramid is printed at the back.
How the grades differ: Taller pyramids with fewer revealed bricks need more add-and-subtract steps to finish.
Good for: Early arithmetic practice and anyone who likes a quick logic warm-up.
