Is the sum of two negative numbers positive or negative

Two negative numbers add to get negative

Is the addition of two negative numbers necessarily a negative number?

Yes. The simple proof is as follows:
Let a and B be two positive numbers, so - A and - B are negative numbers
（-a)+(-b)=-(a+b)
Because a + B must be positive
So - (a + b) must be negative

If the sum of two numbers is negative, then what are the two numbers?
1: It must all be negative
2: It can be all positive numbers
3: It's always positive and negative
4: There is at least one negative number

The answer is 4
1. Why not
Minus five plus four is minus one
2. Why not
The sum of two positive numbers equals a positive number
3. The reason for the mistake
Minus one plus minus one and minus two

List eight eights to get 1000
8 8 8 8 8 8 8 8 = 1000

8,8,8,8,8,8,8 from these eight numbers, 1000 is calculated
1:((8*8*8-8)*(8+8))/8-8
2:((8+8)*8-(8+8)/8)*8-8
3:(8*8-(8+8)/8)*(8+8)+8
4:((8+8)-8/(8+8))*8*8+8.Fraction
5:((8+8)*8-(8+8+8)/8)*8
6:(8-8/(8*8))*(8+8)*8-8.Fraction
7:((8+8)*8-8/8)*8-(8+8)
8:(8*8+8*8)*8-(8+8+8)

The sum of eight eights should be equal to 1000?
Can only add, can not use other symbols Oh!
