How do I get Maple to go into 1-d input?

Choosing Maple Input only changes the font color to red, 3^b as it should be displayed is displayed as 3.

This is in Maple 12.01.

Maple should do this

1e123456789876 + 1e123456789876

                           float(infinity)

The answer is 2e123456789876.

Is there a way to get maple to actually do the calculation without doing any manipulation of the numbers before hand?  Maybe there is a package out there for working with extremely large numbers?

Using a loop to put values into a double indicie, the output table is not organized.

for i from 1 to 4 do
  for j from 1 to 3 do
    a[i,j]:=5*i;
  end do;
end do;

print(a);

table([(3, 2) = 15, (3, 3) = 15, (4, 1) = 20, (4, 2) = 20, (2, 2) = 10, (1, 2) = 5, (2, 1) = 10, (1, 3) = 5, (1, 1) = 5, (3, 1) = 15, (4, 3) = 20, (2, 3) = 10])

Guys, I'm stuck on a simple silly problem.  I suppose I have one of those senior moments but in any case  ...

All I was trying to do was derive an equation from a simple word problem I made up.  Specifically it has to do with the fact that it's costing me more to buy efficient energy saving flourescent bulbs than to use those ever so energy inefficient incandescent bulbs.  But it turns out those inefficient bulbs is the cheaper route.

Basically it's a cost analysis problem.  Anyways here's how it goes. 

Never actually came across this yet. 

I'm using writedata and I'm getting an Error, in (fopen) permission denied.

How do I know where Maple is writing to?  I'm guessing a folder is read only somewhere.  Any ideas?
