Let's multiply 31 x 31.

Multiply the numbers with each other and then double it. 3 x 1 = 3.

Multiply the numbers on the Right, 1 x 1 = 1

So your answer becomes 961.

So how about 81 x 81?

Accommodate the 1 in 64, so that gives us 65, because your middle is a 2 Digit Number

That's all

Fun, right.

How about 91 x 91?

How cool is that 🤯
