Write it, run it, read the output

This is a scratch drill — your code runs, nothing is graded or recorded. No test cases, no expected output, no verdict.

TASK

Using a = 17 and b = 5, print the result of +, -, *, /, and % in separate statements. Then reset a to 17, apply standalone increment and decrement statements, and print the resulting values.

a + b = 22
a - b = 12
a * b = 85
a / b = 3
a % b = 2
+a = 17
-a = -17
a after a++ = 18
a after a-- = 16
