a negative plus a negative =?

Example
(- 4) + (- 3)

On number line, the thinking is :-
Start at zero
4 steps LEFT
THEN
3 steps LEFT
Now at 7 steps LEFT
Answer is then -7

(- 4) + (- 3) = (- 7)

these are the actions of signs + and - while solving algebaric equations:
negative + positive = negative
negative + negative = positive
positive + positive = positive
positive + negative = positive

however the sign of the greater number is always carried in the answer, such as:

-8 + 15 = 7 (greater number is 7 and its sign is +)

-9 + (-10)
-9 -10 = -19 (greater number is 10 and its sign is -)

10 + 4 = 14 (greater number is 10 and its sign is +)

RE:
A negative plus a negative =?
i know a neg times a neg = a + but is it the ame for subtraction and addition?

A negative plus a negative is always negative no matter how big the numbers are.

b = positif number
c = positf number

-b + (-c) = -b-c = -(b+c) = negatif number.

So, a neg number plus a neg number is equal to a neg number.
