2. Hello, C++programmerinCali!

It took a while to get what you were saying
. . You left out a decimal point.

$(0.121121112...) + (0.545545554...) \:=\: \_\_\_\_$ . shows what important concept?

The two decimals are irrational numbers.
. . but their sum is $0.66666... =\tfrac{2}{3}$ . . . . a rational number.

. . . that the sum of two positive irrational numbers can be rational ?
