When something is equal to something else, then they have the same value. For instance, if , then
belongs to the set of numbers {4}. You are also able to use this to prove other statements.
Question: Given that , prove that
.
Solution: We can first square our original equation to get . We can add
to that, as we know that
still equals
. So,
. We can also subtract both the left and the right side of the equation by
, giving us
. This proves what we wanted to prove.
