Question

I need this written in an algebraic expression: Half the difference of a number and it's opposite

Answer 1

[x-(-x)] / 2

Step by step explanation:

Take the number as x.

Its opposite is (-x).

Difference would be:- [x-(-x)]

Half means divided by two, so:- [x-(-x)] / 2

Simplification:-

[x-(-x)] / 2

(x+x) / 2

2x / 2

You can take either the actual answer or the simplified form.
