Question

-b-b сколько будет???

Answer 1

-2b так как это можно записать так -b+(-b)

Answer 2

Будет -2b

-b-b=-b+(-b)=-2b

Answer 3

The expression "-b-b" seems to contain subtraction operations between the variables "b" and "b." In this case, the result would be zero.

To explain it step by step:

1. -b: This means the negation of the variable "b," so if "b" is a positive value, then "-b" will be negative, and if "b" is negative, then "-b" will be positive.
2. -b - b: Now we subtract "b" from the result of "-b." Since "-b" and "b" are of the same value but opposite signs, their sum will be zero.

So, the answer is 0.
