Zero conditional: explain a regular result
Imagine a working display with a charged battery. This button always activates its screen. Explain that regular response to a friend.
Professor Scott MendozaThe short answer
A zero conditional can describe what regularly happens when a condition is met: If I press this button, the screen lights up. Both clauses use the present simple. Here the speaker explains how this device works, not one particular future plan.
Connect a condition to its regular result.
The if part gives the condition: I press this button. The other part gives the result: the screen lights up. Keep ordinary present-simple agreement: I press, but the screen lights. This pattern also works for everyday routines, not just scientific facts.
How this display behaves
If I press this button, the screen lights up.
The screen lights up if I press this button.
If the battery is empty, the screen stays dark.
When the if clause comes first, put a comma after it. With the result first, normally leave out that comma.

The display works this way every time its battery is charged. Choose the correct present-simple pattern.
If I press this button, the screen lights up.I press and the screen lights use correct present-simple forms. The other choices have incorrect verb combinations or agreement.
In “If I press this button, the screen lights up,” what does the stated display context describe?
The device’s regular response.In this context it is the regular response of the device, not a single future plan or one past event.
Put the result first, using standard punctuation without an unnecessary comma.
The screen lights up if I press this button.Keep the subject I before press. A following if clause normally needs no comma in this sentence.
Put it into practice
Fix the device instruction.
Use standard punctuation after the initial if clause and correct present-simple agreement. Fix both details.
If I press this button the screen light up.

Common questions
A few useful details before you move on.
Does zero conditional mean a rule has no exceptions anywhere?
No. A statement can describe a routine or a relationship within a stated situation. Make the context honest; the grammar alone does not prove a universal fact.
If I work late, I order dinner.
Why not use will here?
Will can describe a particular expected future result. The exercise asks for the regular present-simple pattern; it does not claim that every conditional with will is wrong.
If I have time tomorrow, I will test the screen.
Take it into your day
For this regular result, use present simple in both parts and preserve the subject–verb agreement.
