Can someone explain to me why in Section 4: Functions they compute Twice by multiplying the number by three then subtracting the number once? Is it just to showcase more math, or is there a detail I'm missing?
> /*
Computes double of a number.
Works by tripling the number, and then subtracting to get back to double.
/
static int Twice(int num) {
int result = num * 3;
result = result - num;
return(result);**
"Due to the telecommunications landscape right now, it may not be possible to seamlessly maintain your primary number for all instances, for example it is not possible to forward messages with most carriers we have explored."
This pretty much kills it IMO. When someone is trying to reach you they have to message two numbers?
