There are infinitely many possible answers, for example,
0.1 + 27.9
0.2 + 27.8
0.3 + 27.7 and so on
or
0.01 + 27.99
0.02 + 27.98 and so on
or numbers to 3, 4, infinitely many decimal digits.
1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+13
and similar examples which, when you allow negative numbers, can be infinitely long.
Next, there are multiplications:

30. 28 x 30 = 840
28 = 1 x 28, 2 x 14, 4 x 7.
28 multiplied by 30 is 840.
3x + 7 = -4x + 28 implies 7x + 7 = 28
128
It Equals 28. If You Do 7x4 It Will Say 28.
40-n equals 28 = 12

30. 28 x 30 = 840
28 = 1 x 28, 2 x 14, 4 x 7.
7x4 equals 28.

-A = 28 A = -28 because -(-28) = 28
28 multiplied by 30 is 840.
3x + 7 = -4x + 28 implies 7x + 7 = 28
