They equal a minus and two +'s or two -'s equal a + :)
Terms are in expressions that separate by plus or minus signs. The answer is TERMS.

It mean that there is no correlation between the two variables. The variables are the same.

Yes, and it would be a negative slope.
Same mathematical signs equal plus Different mathematical signs equal minus Plus Plus = Plus (+)(+) = + Minus Minus = Plus (-)(-) = + Plus Minus = Minus (+)(-) = - Minus Plus = Minus (-)(+) = - So the direct answer to your question would be: plus minus equals minus

Because both minus signs to be cut therefore minus * minus will be treated as plus numbers
NO!!!! Here is a table for multiplication/division of 'double (+/-) signs.'. (+)(+) = (+) (+)(-) = (-) (-)(+) = (-) (-)(-) = (+) Sometimes in higher level maths, you can have triple signs. Here is the table. (+)(+)(+) = (+)(+) = (+) (+)(-)(-) = (-)(+) = (-) (-)(+)(+) = (-)(+) = (-) (-)(-)(-) = (+)(-) = (-) It is irrelevant on the position of the 'sign'. NB If no sign is given, then read it as positive (+).

Plus and minus.
A plus times a plus is still a plus. Below is the way I remembered it: If there is not a minus sign, it is plus (positive). If there is 1 minus sign, it is minus (negative). If there are 2 minus signs, it is plus (positive).

+/- means that the answer can be either a positive(+) number or a negative(-) number. e.g. the sqrt(4) = +/- 2 Because +2 x +2 = 4 & -2 X -2 = 4 Similarly for any other square root values.
