I have a program that generates and outputs a sequence of simple sample math homework tasks, like:

1 + 1 = ...
3 + 3 = ...
2 + 5 = ...
3 + 7 = ...
4 + 2 = ...

a sequence can be quite long, and I'd like to save space when this sequence is printed by converting it as follows:

1 + 1 = ... 3 + 7 = ...
3 + 3 = ... 4 + 2 = ...
2 + 5 = ...

that is, wrapping the lines into the two or more columns. I was expecting the column linux utility to do the job using the -c N option witn N=2, however, it still outputs the lines in one column whatever the N is.

How would I do the column-ifying of the sequence of lines?
