Answer:
2. -(-73) is positive
Step-by-step explanation:
It's not too difficult, but you can get wrapped around the axle. Here are the rules:
- the opposite of a positive number is a negative number
- the opposite of a negative number is a positive number
That is, turning a number to its opposite is just changing its sign.
__
If you layer these rules, you find ...
the opposite of (<em>the opposite of a positive number</em>) is a positive number
The first rule tells you <em>the statement in parentheses is a negative number</em>, and the second rule tell you its opposite is a positive number.
That is, a double opposite gets you back where you started. In short, <em>any even number of minus signs cancel each other</em>.
__
The numbers you have listed here* are ...
- -730 (negative)
- -(-73) = 73 (positive)
- -75 (negative)
- -(-(-701)) = -701 (negative)

* We say "listed here" because we're seeing mismatched parentheses and brackets, so we know something is missing. We're going by the signs and numbers that we do see. YMMV
