111111111 x 111111111 = 12'345.6789876, "Hope that helps."
you can get the square of any number which contain only 1, like: 11 or 11111111 with the thrick below, & of course there would be no need for any kinda calculator.
11*11=121
111*111=12321
1111*1111=1234321
got it ? just count how many times 1 has been repeated in the number, for instance in the last case it's been repeated 4 times. then simply write 1 2 3 4 3 2 1.
this cutoff has no limitation in frequency of 1 in the number.
& Done.
111111111 × 111111111 = 1.234567899×10¹⁶
12345678987654321
