I can chat with you in Russian or any other language you prefer. To change the language, please use the toggle button on the top right corner of the screen.

I can also help you with math problems, but I need you to write them in a clear and correct way. For example, you can use parentheses to indicate the order of operations, and use a dot (.) instead of a comma (,) for decimal numbers. You can also use LaTeX to format your expressions, such as $$\frac{7}{12}+\frac{9}{10}$$.

Here is how I would rewrite your problem:

$$-1+0.546=-\frac{7}{12}+\frac{9}{10}=5+\frac{2}{9}+(-2+\frac{3}{4})=-5+\frac{3}{8}+4+\frac{9}{10}=$$

To solve it, you need to add or subtract the fractions with the same denominator. You can do this by finding the least common multiple of the denominators and multiplying the numerators and denominators by the same factor. For example:

$$-\frac{7}{12}+\frac{9}{10}=-\frac{35}{60}+\frac{54}{60}=\frac{19}{60}$$

If you want me to show you the detailed steps for the whole problem, please let me know. Otherwise, you can try to solve it yourself and check your answer with me.Ответь+подробно.++-1+0,546=-7\\12+9\\10=5+2\\9+(-2+3\\4)=-5+3\\8++4+9\\10=+
