This Challenge is to utilize Global variables.

Global variables are risky as the subroutine may inadvertently and unwantingly update them. Globals also tend to slow execution time.

The Challenge is to implement and become aware of capability and risk.

The global variables in this Challenge are gOffset and global_x.

Given two input variables [a,b] output [gOffset+a global_x*b]

Input: [a,b] (Two real values)

Output: [gOffset+a global_x*b]

Related Challenge is Persistent.
