We start with a clear introduction to number pyramids, explaining the basic addition and subtraction rules that govern how the blocks stack up. From there, we move into a hands-on practice session where you'll learn strategies for filling in the blanks when key numbers are missing, helping you build strong mental math and logical reasoning skills. Finally, we take things a step further by introducing algebra grids, showing you how to translate these visual patterns into basic algebraic equations to find unknown values easily.
