Question

1. The sum of two integers cannot be 0, True or False?

2. The sum of two negative integers is always a negative integer, True or False?
3. What number must you add to -6 to get a sum of zero

Answer 1

1) false example -1+1=0

2) true

3) 6

Answer 2

`\huge\boxed{\text{1. False}}`

Integers are the numbers in the set
`{..., -3, -2, -1, 0, 1, 2, 3, ...}`. This means that you can add two opposite integers to get
`0`.

For example,
`-3+3=0`.

`\huge\boxed{\text{2. True}}`

When you add a negative number to another negative number, the only thing that can happen is that the result goes down.

For example,
`(-3)+(-2)\ =\ -3-2\ =\ -5`.

`\huge\boxed{\text{3. 6}}`

Let's write this as an equation, where
`x` represents the unknown value.
`-6+x=0`

We need to isolate the variable by adding
`6` on both sides of the equation.
`x=\boxed{6}`
