I imagine that was shown in the YouTube video visually? That it's a hypotenuse like he explained and this is how to calculate it. I'm just not seeing evidence that he came to the idea of it being like that on their own.
He basically reiterated the definition, and had to know the formula.
If the child would explain why should we even use or have complex numbers that would be impressive. As otherwise it just seems nothing more than hypotenuse calculation while using different, and "complex" or "impressive" sounding terms.
Why should you be interested in this in the first place?
