Hey!
First, let's write the problem.
[tex]2-\left(-8\right)+\left(-3\right)[/tex]
We know that, [tex]-\left(-8\right)=+8[/tex], so let's apply that
[tex]=2+8+\left(-3\right)[/tex]
We have to add, [tex]2+8=10[/tex]
[tex]=10+\left(-3\right)[/tex]
We know that [tex]+\left(-3\right)=-3[/tex], so let's apply that.
[tex]=10-3[/tex]
Subtract. [tex]10-3=7[/tex]
[tex]=7[/tex]
Our final answer would be 7!
Thanks!
