Start writting vs Start to write

???? ?????? Could you please to describe the difference between these sentences?

???? ??????Start writting it's number or name vsStart to write it's number or name

These are not sentences, and they don't make much sense. I suggest you rewrite them.

To find some item start writting it's number or name
To find some item start to write it's number or name

Thank you!

There is no apostrophe in possessive its, and only one t in writing.

Apart from these slips, both sentences are fine. There is no significant difference in meaning between them,

???? ??????To find some item start writting it's number or nameTo find some item start to write it's number or nameThank you!

Here's my guess.

To find an item, start by writing its number or name.

CJ

To find an item, start writing its number or name
To find an item, start to write its number or name
To find an item, start by writing its number or name

Which of the sentences is correct? or can I use any?

Thank you!

???? ??????Which of the sentences is correct?

If you put a period at the end of them, they are all correct.

1 and 2 mean one thing, and they both mean the same thing, namely that you should start the process of writing (the number or name) in order to find an item, as if just beginning to do that would result

Your reply very clear!
Thank you a lot!
