Final answer:
If A is equal to B and B is equal to C, then A is equal to C.
Step-by-step explanation:
In mathematics, if A is equal to B and B is equal to C, then we can deduce that A is equal to C. This is called the transitive property of equality.
For example, if A = 2, B = 2, and C = 2, then we can say that A = C.
