Any *bounded* Level 1 interval. At level 1 a+b and a-b don't exist
when either a or b is infinite. At level 2 the only possible mid-rad
result is Entire, which loses almost all information unless the level 1
interval was Entire too (in which case a+b does not exist at level 2,
so a special rule would be followed).
