(41 * 134+11 978): (1211-899) =

Let's calculate the expression step by step:

First, we calculate the multiplication inside the first parentheses:

$$41 \cdot 134 = 5494$$

Next, we add 11978 to the result:

$$5494 + 11978 = 17472$$

Now, we calculate the subtraction inside the second parentheses:

$$1211 - 899 = 312$$

Finally, we divide the first result by the second result:

$$17472 : 312 = 56$$
