After a second or two, I know what's going on with this multiplication, but I feel unable to apply the same methodology when one of the numbers has greater than two digits (e.g., 2 digits x 3 digits) without demonstration.
Yeah, it's a rather advanced form of multiplication. This is actually the first time I've ever seen it. Keine will certainly explain it all for us...after she cleans up the mess Cirno's head makes after it explodes from seeing this.
