PROGRAM EXPLANATION
Algorithm and explanation
- Assign a = 17 and b = 5; this example does not read keyboard input.
- Evaluate a + b = 22, a - b = 12 and a * b = 85.
- Evaluate a / b = 3.4; Python true division returns a float for these integer operands.
- print displays the four results in order, separated by spaces.
The output 22 12 85 3.4 follows the order of the four expressions passed to print. Changing a or b changes the results without changing the operator meanings. The / operator performs true division, while // performs floor division: 17 // 5 is 3, but -17 // 5 is -4 because the result is rounded toward negative infinity. Dividing by zero raises ZeroDivisionError. The O(1) label describes this fixed-size demonstration; arithmetic on arbitrarily large Python integers can require increasing time and memory.

DEBUGGING CHECKLIST
Common mistakes
Do not confuse / with //: they have different results and meanings.
Set b to a non-zero value before evaluating a / b.
Predict results in expression order; print does not reorder them.
