I can chat with you in Russian.

To round a number to the nearest hundredth, you need to look at the digit in the thousandths place. If it is 5 or more, you add 1 to the digit in the hundredths place and drop the rest of the digits. If it is 4 or less, you keep the digit in the hundredths place and drop the rest of the digits.

For example, to round 580,7744 to the nearest hundredth, you look at the 4 in the thousandths place. It is 4 or less, so you keep the 7 in the hundredths place and drop the rest of the digits. The result is 580,77.

Here is the mathematical expression for rounding 580,7744 to the nearest hundredth:

$$\lfloor 580,7744 \times 100 + 0,5 \rfloor \div 100 = 580,77$$

The symbol $\lfloor x \rfloor$ means the largest integer that is less than or equal to x. The symbol $\div$ means division.
