There are infinitely many possible additions:
10+11, 9+12, 8+13, 7+14, ....
and then
10.5+10.5, 10.4+10.6, 10.3+10.7, 10.2+10.8, ....
and then 2 digit
10.49 + 10.51, 10.48+10.52, ...
and 3 digit, 4 digit, ... infinitely many digits.
Next, you can look at multiplication:
1x21, 2x10.5, 3x7, and so on
and then 0.1x210, 0.2*105, 0.3*70 and so on
and then 2 digit decimals fractions, and then 3 digit, 4 digit, and so on, and on.
And I have not even started on 3 or more numbers, or powers and other mathematical functions.
