Consider the expression: 3 // 4 * 20 + 6 / 2. What value does this expression reduce to? Be sure to list a literal of appropriate type (e.g., 7.0 rather than 7 for a float, string literals in quotes).

BlackTom AI · Accepted Answer

To tackle the expression, begin by identifying the operators and their precedence. The expression is 3 // 4 * 20 + 6 / 2, which uses floor division //, multiplication *, addition +, and true division /.

First, evaluate 3 // 4. Floor division takes the quotient and rounds down to the nearest integer, so 3 // 4 equals 0.

Next, multiply the result by 20: 0 * 20 equals 0.

Then compute 6 / 2. Division with a single slash yields a floating-point result in Python, so 6 / 2 equals 3.0.

Finally, add the two parts: 0 + 3.0 equals 3.0.

Therefore, the expression reduces to the literal 3.0, matching the required numeric type for a float result.
