To estimate $$ 23.06 + 5.9 + 0.989 $$ mentally, we can round each number to the nearest whole number:

- $$ 23.06 $$ rounds to $$ 23 $$
- $$ 5.9 $$ rounds to $$ 6 $$
- $$ 0.989 $$ rounds to $$ 1 $$

Now, we can add these rounded numbers together:

$$
23 + 6 + 1 = 30
$$

Thus, $$ 23.06 + 5.9 + 0.989 $$ is approximately equal to $$ 30 $$.
$$ 23.06 + 5.9 + 0.989 $$ is approximately equal to $$ 30 $$.
