Concat Two Int Columns Into One

I got a access SQL question.

Let's say we have two int columns, I want to get the results Column1 + Column2 in string format

i.e

Column1 - Column2
5 - 2
6 - 2.5
10 - 6.5
10.5 - 8


I need to return the data as new column like:

NewColumn
"5 to 2"
"6 to 2.5"

so on

SQL + operator only works for string operation, how would I use it for numeric data type.

Thanks a bunch
