To solve the given problem, let's break it down step-by-step. You have three numbers associated with various operations:
1. The first number is [tex]\(4\)[/tex].
2. The second number is [tex]\(-20\)[/tex].
3. The third number is a bit unclear because it contains "S2 [tex]$=0" indicating that the third component in some operation results in zero. But, due to other clues, we'll assume the third number is \(2\) for operating purposes.
Given these three numbers, we need to perform the following operations:
1. Addition of the three numbers:
\[
4 + (-20) + 2 = -14
\]
2. Multiplication of the three numbers:
\[
4 \times (-20) \times 2 = -160
\]
3. Setting a number to 0 based on the context "S2 $[/tex]=0" is interpreted simply as assigning the value zero to the output of one operation:
[tex]\[
0
\][/tex]
Thus, the results of these operations are:
- Addition result: [tex]\(-14\)[/tex]
- Multiplication result: [tex]\(-160\)[/tex]
- Assignment or setting of a number to zero: [tex]\(0\)[/tex]
So, summarizing the results:
[tex]\[
\text{Addition: } -14, \text{ Multiplication: } -160, \text{ Setting to zero: } 0
\][/tex]
