Answer

To solve the expression `15 - 3 + 10 x 5 + 5` with the given sign meanings, we will first replace each sign according to the rules provided:

1. **Replace the signs:**
- The sign '-' means '+'
- The sign '+' means '-'
- The sign 'x' means '+'
- The sign '+' means 'x'

Therefore, we will rewrite the expression as follows:
- `15 - 3 + 10 x 5 + 5` becomes `15 + 3 - 10 + 5 x 5`

2. **Now, rewrite the expression:**
- `15 + 3 - 10 + 5 x 5`

3. **Next, perform the multiplication:**
- The multiplication `5 x 5` becomes `25`.
- So, the expression now is `15 + 3 - 10 + 25`.

4. **Now, simplify the expression step by step:**
- First, we add `15 + 3` which equals `18`.
- The expression now is `18 - 10 + 25`.

5. **Next, perform the subtraction:**
- `18 - 10` equals `8`.
- The expression now is `8 + 25`.

6. **Finally, perform the addition:**
- `8 + 25` equals `33`.

Thus, the simplified result of the expression `15 - 3 + 10 x 5 + 5` is **33**.
