This would be the help you need on learning when to use each of the 'to's', and also that you cannot just use a number in place of to or too. As always, it's rather annoying, and just puts a big flashing sign over your head that says 'idiot'.
As you can plainly see, there is a place and a use for each of these words.
To is the most commonly used of the three. Use it when you're not talking about a number value (two, 2) or a quantity (too). It's used when talking about a direction toward or away from something [
I went to the store. - She could see all the way to the bottom.]
Too is used when talking about a quantity or extremity of something. [
My brother came, too. - He was too angry to talk about it.]
Two, most obviously a number. This is the only one of the three 'to's' that you may substitute and use the number (2). [
There are two red apples.]
