**Form as many horizontal-style arithmetical expressions as possible that equal 1,000.**

In order to limit the total number of possible solutions, the following rules of mine are in place:

----------------------------------------------------------------------------------------------------------------------------

Use exactly six sixes.

Use no more than one pair of parentheses.

Use no more than one "/" symbol.

Use no more than two decimal points.

Use no more than one minus (subtraction) sign.

Concatenation **is** allowed.

No other symbols/characters/operations are allowed.
