Adding a common international number to 700 mbl numbers

[handerz]

I am new to Alteryx and have been trawling the community to try and find an answer to the above issue.

I am working with a large mbl data set and need to add the "44" code infront of the numbers, as this will soon be used as I identifier as I merge data downstream.

I belive I need to use the formual tool within the preparation section and select 'Mobile' under the exisiting feilds but I am then at a loss.

Any hlep is much apprecaited.

If all values are numbers of equal length (7),

440000000+[number]

otherwise 

tonumber("44"+tostring([number])

if the number is already a string:

"44" + [number]

is this a good start?

Thankyou very much the first suggestion was spot on.
