Hong KongCan you use a calculator?
A basic on-screen calculator is generally provided and is almost never needed. There are no formulas on this exam. The only arithmetic is counting hours in a cooling window and days for date marking.
Yes, and you will not need it.
What arithmetic actually appears
- Date marking. Seven days, with the preparation day counting as day one.
- Cooling. Two hours to 70°F, four more to 41°F, six total.
- Time control. Four hours from leaving temperature control, or six under the colder start rule.
- Corrective actions. Whether something has been out of temperature for more or less than two or four hours.
All of it is counting. No conversions, no percentages, no formulas.
The one that catches people
Date marking, because of the day-one convention. Food prepared on the 1st is discarded at the end of the 7th, and almost everyone counts to the 8th the first time.
That is an off-by-one error rather than a calculation, and a calculator does not help with it.
Temperature conversions
Not required. Questions state temperatures in the units they intend, and where both appear it is as a pair rather than as something to convert.
Learning the pairs - 41 and 5, 135 and 57, 165 and 74 - is more useful than knowing the conversion formula, and considerably faster under pressure.
Bringing your own
No. Personal calculators, phones and smart watches all go in the locker. The on-screen one is what is available.
What to do instead
Read the clock times in the question carefully. Most time questions are decided by noticing when the clock actually started - when food left temperature control, not when service began.
That is a reading task, and it is where the marks in this area are won and lost.
Common questions
Is a calculator allowed on the food manager exam?
A basic on-screen calculator is generally provided. Personal calculators, phones and smart watches go in the locker.
Is there maths on the food manager exam?
Only counting - hours in a cooling window, days for date marking, and whether food has been out of temperature for more or less than two or four hours. No formulas.
Do you need to convert temperatures?
No. Questions state temperatures in the units they intend. Learning the pairs - 41 and 5, 135 and 57, 165 and 74 - is faster than knowing a conversion formula.
What is the most common arithmetic mistake?
Date marking counted from day zero, which produces eight days instead of seven. It is an off-by-one error rather than a calculation, and a calculator does not help.
How do you get time questions right?
Read when the clock actually started. Most are decided by noticing that time runs from when food left temperature control, not from when service began.
