[STRIKE]Dear teacher,[/STRIKE] Unnecessary. You can just say "Hello".
Is it possible to use these words [strike]at the same time[/strike] together - "more than several times"? Please clarify this for me.
Welcome to the forum. :hi:
Please note that I have changed your thread title. I have no idea why you called it "Mr". Thread titles should include some or all of the words/phrases you are querying. Also note the changes I have made to your post above, marked in red. It's important to use correct punctuation.
As far as "more than several times" is concerned, it might be usable. Please give us a complete sentence to consider.
