Question

111111111×111111111=​

Answer 1

Answer:

111111111 x 111111111 = 12345678987654321

Step-by-step explanation:

The equation above shows the pattern that you get when you square a number with all ones in it. The representation below is in the form of a triangle that starts at the top with the square of the number 1 and ends up at the base with the square of the number containing 9 ones. Notice the symmetry for each row. The number of ones in each number on the left equals the middle number of the square on the right. The symmetry here can only be represented for numbers contain up to 9 ones. When you get to a string of 10 ones or more the pattern changes.
