Expert Solution

Step 1

Given expression:

(~5+~0)*6 == 3+3*~0

Among the operators used in the given expression, paranthesis has highest precedence followed by ~, followed by *,/ followed by +, - followed by relational operators(here ==)

(~5+~0)*6 == 3+3*~0

(0+1)*6 == 3+3*~0

1*6 == 3+3*1

6==3+3

6==6 (True)

So, the value of the expression (~5+~0)*6 == 3+3*~0 is 1
