(1111)(9999) = (1111)(10000 - 1) = 11110000 - 1111 = 11108889

Brilliant. Makes me feel stupid for knowing how to factor quadratics.

This is what I did. Much better than trying to multiply 9 by the square of 1111.

@@jonathantremel3732 It's what happens when you make the problem. You don't see other solutions. It was obvious that he was trying to include several different tricks to make and solve a problem, like Difference of Squares and the 11^2 = 121 thing.

Thanks to you'll 🙏 The answer was entered on my cellphone.

Simpler: You've got a Pythagorean triple. 5^2 - 4^2 = 3^2 So K*5^2 - K*4^2 = K*3^2 Let K= 1111^2 and combine the squared product terms. 5555^2 - 4444^2 = 3333^2 [Edit: Basically what Leo said below.]

My dumbass would have just brute forced the squares and add them together.

I went to geometry, so I learned Difference of Squares, but walterwen2975 (comment below) shares a very elegant solution that I didn't think of, because I was restricted by the monotony of the school curriculum.

I got all these steps but I was waiting for a trick for the last step. No trick there

It's better to write (1111*5)²-(1111*4)² Which will lead you to 1111²(25-16) 1111²(9) Then rewrite 9 as 3² as commonly applied on Pythagorean theorem applications 1111²(3²) And re write the expression 3333² Which is equal to the solution provided in the video, but it comes to show a beautiful expression
