Also, too and as well

The adverbs also, as well and too have similar meanings, but their placement in the sentence is different.

- Also is used with the verb: 
   before the verb unless it's to be or a modal verb (can, may, must, should...). 

- Too and as well usually go at the end of a sentence or clause, but too can also be placed in the middle of the sentence, between commas. When it (too) is placed at the end of the sentence, a comma should be placed before. As well is placed at the end of a sentence or clause after no comma.
