Not necessarily. For as long as the first two and the second two are alike, they come together to equal four. They can never equal five (or any other random number), but if they are ever not alike, then at that time, they can only ever equal two and two, without ever coming to four.
For example, 2 apples plus 2 apples = 4 apples.
2 apples plus 2 oranges = 4 fruits, but only two apples and two oranges - never four of each, nor four of either.
2 apples and 2 rabbits can only = 2 apples and 2 rabbits - they don’t have enough in common to become four of anything.
Mathematically, 2+2=4, all the time - this is a fact. But as soon as you begin to apply meaning (truth) to it, then it becomes ambiguous - you have to know what it is that you are counting, before you know for certain whether it is true or not.
That isn’t relativism, though - that’s just the practical application of the mathematical principle.
