Question

12,91+(-12,91)-18,01-(-16,435)-(+9,365)

Answer 1

12,91-12,91-18,01+16,435-9,365=-10,94

Answer 2

Let's break down the expression step by step:

1. 12.91 + (-12.91): The sum of a number and its negative is always zero. So, 12.91 + (-12.91) = 0

2. 0 - 18.01: Subtracting 18.01 from 0 gives us: 0 - 18.01 = -18.01

3. -18.01 - (-16.435): Subtracting a negative number is equivalent to adding the positive value. So, this becomes: -18.01 + 16.435 = -1.575

4. -1.575 - (+9.365): Subtracting a positive number is equivalent to adding the negative value. So, this becomes: -1.575 - 9.365 = -10.94

Therefore, the final result of the expression is -10.94.
