According to a calculator, the answer is 1e+32

----------------------------------------------------------

Calculators do not have enough precision to do this calculation correctly.

You must do it by hand:

Calculate the sixteen partial products.

0000000000000009 * 9999999999999999 = 00000000000000089999999999999991

0000000000000090 * 9999999999999999 = 00000000000000899999999999999910

0000000000000900 * 9999999999999999 = 00000000000008999999999999999100

0000000000009000 * 9999999999999999 = 00000000000089999999999999991000

0000000000090000 * 9999999999999999 = 00000000000899999999999999910000

0000000000900000 * 9999999999999999 = 00000000008999999999999999100000

0000000009000000 * 9999999999999999 = 00000000089999999999999991000000

0000000090000000 * 9999999999999999 = 00000000899999999999999910000000

0000000900000000 * 9999999999999999 = 00000008999999999999999100000000

0000009000000000 * 9999999999999999 = 00000089999999999999991000000000

0000090000000000 * 9999999999999999 = 00000899999999999999910000000000

0000900000000000 * 9999999999999999 = 00008999999999999999100000000000

0009000000000000 * 9999999999999999 = 00089999999999999991000000000000

0090000000000000 * 9999999999999999 = 00899999999999999910000000000000

0900000000000000 * 9999999999999999 = 08999999999999999100000000000000

9000000000000000 * 9999999999999999 = 89999999999999991000000000000000

Sum the partial products.

9999999999999999 * 9999999999999999 = 99999999999999980000000000000001
