Which is correct?

Make it equal to zero.

Or

Make it equals to zero.

I think the second one is correct.

No. The first one is correct.

I had to think about this for a while -- until I figured that "equal" is used as an adjective, not a verb, in this sentence.

Consider these similar constructions:

Make it safe.
Make it colorful.
Make it beautiful.

Thank you, Ms. Sue.

What about "Makes it equal to zero" then again i don't know the context.

The correct phrase is "Make it equal to zero." The second option, "Make it equals to zero," is not grammatically correct.

To determine which is correct, let's break down the sentence:

- "Make" is an imperative verb that indicates a command or instruction.
- "It" is a pronoun that refers to something previously mentioned or understood.
- "Equal to zero" is a phrase indicating the desired result.

When using the verb "make" in this context, we use the base form ("equal") after it and not the third-person singular form ("equals"). So, the correct sentence is "Make it equal to zero."
