7055*60+49610:82*104

To solve the mathematical expression given:

7055 * 60 + 49610 ÷ 82 * 104

First, we should follow the order of operations, also known as PEMDAS/BODMAS (Parentheses/Brackets, Orders/Indices, Division and Multiplication, Addition and Subtraction). In both cases, division and multiplication are at the same hierarchical level and should be carried out from left to right.

So, we deal with the multiplication and division first:

1. 7055 * 60 = 423300
2. 49610 ÷ 82 = 605 (rounded down since 605.4878 is the exact result and we cannot continue with decimals in the next multiplication step)

Now, multiply the result of the division by 104:

3. 605 * 104 = 62920

Finally, we add the result of the multiplication (step 1) to the result of the multiplication in step 3:

423300 + 62920 = 486220

Therefore, the result of the expression is 486220.
