Question

what is the value of the variable result after these lines of code are executed?

>> a = 2

>> b = -3

>> c = 4

>> result = (a - b) * c

the value of result is □.

Explanation:

Step1: Substitute values of a and b

First, substitute $a = 2$ and $b=-3$ into $(a - b)$. So, $a - b=2-(-3)=2 + 3=5$.

Step2: Multiply by c

Then, multiply the result by $c = 4$. So, $5\times4 = 20$.

Answer:

20
