# Math Help - How do I represent this mathematically?

1. ## How do I represent this mathematically?

What is the proper mathematical way to write this simple operation.

So I have a set of numbers [1,2,3]
And I and I want to add 'x' to each element

Pretty straight forward. Thanks!

Dear Vamz,

Define the set $A=\{1,2,3\}$

Let, $B=\{a+x|a\in A,x\in\Re\}$
