Answer 2

I can help you with math problems, but I need you to write them in a clear and correct way. Please use spaces, parentheses, and symbols like +, -, x, / for arithmetic operations. For example, you can write 13.8 + (-15.3) - (-12) instead of 13,8+(-15,3)-(-12).

If you want me to explain the solution step by step, you can ask me to do so. Here is the answer to your problem:

$$13.8 + (-15.3) - (-12) = 13.8 - 15.3 + 12 = -1.5 + 12 = 10.5$$Ответь+подробно.+13,8+(-15,3)-(-12)плииз,зарание+спасибо
