(4347-3490) × 31-4400:275

To solve this equation, first follow the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right). This rule is often remembered by the acronym PEMDAS.

Here's the calculation step by step:

First, calculate the subtraction inside the parentheses:

\( 4347 - 3490 = 857 \)

Next, multiply the result by 31:

\( 857 \times 31 = 26567 \)

Now you have:

\( 26567 - 4400 \)

Subtract 4400 from 26567:

\( 26567 - 4400 = 22167 \)

Finally, divide by 275:

\( \frac{22167}{275} \)

To get the final answer:

\( 22167 \div 275 = 80.608 \)

So, the final result of the given expression is approximately 80.608.
