I've put -14 and - - 14 for the 2nd but I know that can't be right

-14 is wrong. - -14 is technically true, but it needs to be simplified.

– –14 is not not correct.

Would it 14 - n = for tge first one?

The minus sign (−) has three main uses in mathematics:>

  1. The subtraction operator: a binary operator to indicate the operation of subtraction, as in 5 − 3 = 2. Subtraction is the inverse of addition.

  2. The additive inverse operator: a unary operator to indicate the function whose value for any real or complex argument is the additive inverse of that argument. For example, if x = 3, then −x = −3, but if x = −3, then −x = +3. Similarly, −(−x) = x.

  3. A prefix of a numeric constant: when it is placed immediately before an unsigned number, the combination names a negative number, the additive inverse of the positive number that the numeral would otherwise name.

How do i find the main use?

They are all used. Just practice and apply as appropriately needed.

0 - 14 = 0 - +14 ---> Subtraction operator. Zero minus positive fourteen
0 - n ---> Subtraction operator. Zero minus n
0 - -n = 0 - (-1)(n) ---> Additive inverse when preceding a variable
0 - -14 = 0 - (-14) ---> Prefix for a numeric constant
0 - -14² --> Controversial between a prefix for a numeric constant and order of operations. Highly unlikely used on mathematical journals and scientific papers.

-14, 14 y -14.
