Question

A+b-c: (a-2b) блок схема

Answer 1

Вот так, вроде. В принципе, да.

Answer 2

Creating a block diagram for the expression "A + B - C - (A - 2B)" can be done using standard flowchart symbols. Below is a simple block diagram for this expression:

  +---------+       +---------+     +---------+
  |    A    |       |    B    |     |    C    |
  +----+----+       +----+----+     +----+----+
       |                 |               |
       |                 |               |
       +--------+--------+               |
                |                       |
                |                       |
          +-----v-----+                 |
          |    -     |                 |
          +-----+-----+                 |
                |                       |
                |                       |
        +-------v-------+               |
        | A - 2 * B     |               |
        +-------+-------+               |
                |                       |
                |                       |
          +-----v-----+                 |
          |    -     |                 |
          +-----+-----+                 |
                |                       |
                |                       |
           +----v----+                  |
           |   +   |                    |
           +----+---+                    |
                |                        |
                |                        |
          +-----v-----+                  |
          |    -     |                  |
          +-----+-----+                  |
                |                        |
                v                        v
         +------+------+        +--------+--------+
         |  RESULT    |        |   FINAL RESULT  |
         +------------+        +-----------------+

Explanation:

1. We have three input variables: A, B, and C.
2. First, we subtract (A - 2B).
3. Then, we add A, B, and C separately.
4. Finally, we subtract the result of (A - 2B) from the sum of (A + B + C) to obtain the final result.

Please note that this is a basic representation of the block diagram, and there can be many variations and optimizations depending on the specific requirements of the problem or the software/tool used to create the block diagram. Additionally, the final output depends on the values of A, B, and C provided as inputs.
