Question

How do you find the sum of `E= ([3 ,4, 7])` and the additive inverse of `G= ([-2, 0 ,5])`?

Answer 1

`[(5,4,2)]`

Explanation:

Additive inverses lead to a zero sum.
Thus the additive inverse of G = `[(-2,0,5)]` is `G prime=[(2,0,-5)]`
Hence required sum `E + G prime` is given by:
#[(3,4,7)]+[(2,0,-5)] =[(5,4,2)]#
