[🟣 Laurie Rubel 🎗️ @Laurie_Rubel]

9 times 9 is 81, and 10 times 8 is 80.
12 times 12 is 144, and 13 times 11 is 143.
5 times 5 is 25, and 6 times 4 is 24.

20 times 20 is 400, so what's 21 times 19?

can you explain why this is happening, without using algebra? (i mean, go ahead with the algebra, if you insist)
