The result will always be 4 because the first four lines of code gets a number [tex]k+4[/tex], where [tex]k=\frac{\text{secret num}}{2}[/tex], and the last line subtracts [tex]4[/tex] from [tex]k+4[/tex].. therefore leaving us with the value [tex]4[/tex].
The effect of each line is explained below:
secret_num = 10
Assigns the value 10 to secret_num
temp = secret_num + 8
Stores the value 18 in temp
temp = temp * 2
Stores the value 36 in temp
temp = temp / 4
Stores the value 9 in temp
answer = temp - secret_num / 2
Stores the value 4 in answer
If the reasoning were done algebraically, we would have
[tex](((\text{secret num} + 8)\times 2)/4)-\text{secret num}/2\\[/tex]
Where the bracket nesting reflects the sequence of operations that led to the final answer in the code
Writing it mathematically, and simplifying
[tex]\frac{2(\text{secret num} + 8)}{4}-\frac{\text{secret num}}{2}\\\\=\frac{2\times\text{secret num} + 16}{4}-\frac{\text{secret num}}{2}\\\\=\frac{\text{secret num}}{2}+4-\frac{\text{secret num}}{2}\\\\=\frac{\text{secret num}}{2}-\frac{\text{secret num}}{2}+4\\\\=4[/tex]
We see that at the end, no matter what the value of secret_num was, the secret_num term still cancels out, leaving us with 4.
