Final answer:
The correct option is b) false.The statement seems to invoke the commutative property of addition, which suggests the arrangement of terms doesn't affect the sum. However, '1A1' and '1B1' as given in the question are not standard mathematical terms, so confirming their relationship without additional context is not possible. Therefore, the answer is False.
Step-by-step explanation:
The statement presented in the question seems to reference a rule similar to the commutative property of addition, which states that A + B = B + A. This is a fundamental concept in mathematics that tells us that the order in which two numbers are added does not change the sum. Therefore, just as 2 + 3 = 3 + 2 in ordinary number addition, if we consider '1A1' and '1B1' to be symbolic representations of numbers or terms in an equation, their order should not affect the outcome if they are part of an addition operation.
However, without additional context on what '1A1' and '1B1' represent, it is challenging to definitively state that '1B1' must always follow '1A1'. If these symbols represent algebraic terms and if the addition operation is done, then yes, by the commutative property, '1B1' can follow '1A1'. However, this question seems to lack the necessary context to provide an accurate answer, as the symbols '1A1' and '1B1' are not standard mathematical expressions or nomenclature.
So the answer to whether there must ALWAYS be a '1B1' following a '1A1' is False, based on the information provided.
