:) you are actually using the direct return value from the decrement function.

\$result-- ; echo ''; and the output is like this: Value now is 8 Add 2, Value now is 10 Subtract 4, Value now is 6 Multiply by 5, Value now is 30 Divide by 3, Value now is 10 Increment by one, Value now is 10 Decrement by one, Value now is 11 Why the value in the last value (increment and decrement by one) is miscalculated? I appreciate all of your effort for helping me, thanks before.. --\$v .'.'; this was the result when Value is now 8Add 2.

Value is now ".\$variable.""; \$variable -= 4; echo "Subtract 4. Value is now ".\$variable.""; \$variable *= 5; echo "Multiply by 5. \$result -= 4; echo ''; echo 'Multiply by 5, Value now is '.
