[tex]\huge\boxed{\text{1. False}}[/tex]
Integers are the numbers in the set [tex]{..., -3, -2, -1, 0, 1, 2, 3, ...}[/tex]. This means that you can add two opposite integers to get [tex]0[/tex].
For example, [tex]-3+3=0[/tex].
[tex]\huge\boxed{\text{2. True}}[/tex]
When you add a negative number to another negative number, the only thing that can happen is that the result goes down.
For example, [tex](-3)+(-2)\ =\ -3-2\ =\ -5[/tex].
[tex]\huge\boxed{\text{3. 6}}[/tex]
Let's write this as an equation, where [tex]x[/tex] represents the unknown value. [tex]-6+x=0[/tex]
We need to isolate the variable by adding [tex]6[/tex] on both sides of the equation. [tex]x=\boxed{6}[/tex]
