Answer 2

WE MUST GIVE AN ALGEBRAIC MEANING to "adding" a negative number:
8 + (−2).
Now, when we add a positive number, we get more. Therefore, when we "add" a negative number, we must get less -- it means to subtract
8 + (−2) = 8 − 2 = 6.
Algebraically, here is the rule:

a + (−b) = a − b
Note that we use parentheses -- a + (−b) -- to separate
the operation sign + from the algebraic sign − . It would
be very bad form to write a + −b.
We are about to learn how to add signed numbers. But first, we must learn how to name the terms.

Naming terms
By applying the rule --
a + (−b) = a − b
-- we can now name the terms of any sum.
Here is a sum of four terms:
1 + (−2) + 3 + (−4).
The terms are 1, −2, 3, and −4.
But according to the rule, we can remove the parentheses:
1 + (−2) + 3 + (−4) = 1 − 2 + 3 − 4.
We say that the sum on the right has the same four terms:
1, −2, 3, and −4.
In other words, we include the minus sign as part of the name of the term. 1 and 3 are the positive terms. −2 and −4 are the negative terms.

When a term appears with no sign in front -- namely the first term, such as 1 -- we must understand it to be positive. 1 = +1.
Again, with positive numbers we typically do not write the algebraic

Answer 6

Good work :) I seem to remember that people sometimes have trouble with the fact that a negative sign and a minus sign is very much the same thing which although it doesn't directly state it here, is what it is saying in a way.

it is ...awsum:)
