My kids were watching it at 5-6. But I believe they don't understand that a staircase number is a sum or a rectangular is a product.

"You don't understand mathematics, you just get used to them"

It really is a genius-level show. I’m so happy it exists. Every detail is just perfect and both my kids love it and have learned so much from it.

It doesn’t hurt that it’s so entertaining they love watching it over and over, making it even more impossible to avoid committing its (very useful) memes to memory!
