Doesn't `9/5` need to be in parenthesis?

I personally suggest a hint of "(9/5) " for the excercise.
Using “/” without a pair of brackets would trigger the error.

Welcome, @tera9960151154,

If we look closely at the list we see no error. The values in the list are all correct conversions.

Operator precedence for division and multiplication is equal so operation is left to right.

y = temp * 9
y = y / 5
y = y + 32
