Question

Write the opposite of each of the following: \[100\text{0 A}\text{.D}\].

Answer 1

Hint: In order to express the opposite of \[100\text{0 A}\text{.D}\] , we must firstly find the opposite of \[\text{A}\text{.D}\] and then we must note down the opposite of \[\text{A}\text{.D}\] as there exists no opposite for a numerical value. So from the given problem, we can understand that only the time period changes while expressing the opposite.

Complete step by step answer:
Now let us learn more about \[\text{A}\text{.D}\]. The full form of \[\text{A}\text{.D}\] is Anno Domini. It is usually used to express the time period or years after the birth of Jesus Christ. The dating of \[\text{A}\text{.D}\] started in \[525\] and it started being adopted in the Western Europe during the Eighth century. Since then the numbering of years as per the Christian Era is currently dominant in many places in the world. The term \[\text{A}\text{.D}\] is used to label the years in the Julian calendar.
Now let us find the answer to the given question i.e. finding the opposite of \[100\text{0 A}\text{.D}\].
As we know that there exists no opposite or the counterpart for numerical values, so the numeric value \[100\text{0}\] will not be changing.
Now let us find the opposite or the counterpart of \[\text{A}\text{.D}\].
The opposite of \[\text{A}\text{.D}\] is \[B.C\] which means Before Christ.
\[B.C\] is the term used to express the time period or the years before the birth of Jesus Christ.
\[\therefore \] The opposite of \[100\text{0 A}\text{.D}\] is \[100\text{0 B}\text{.C}\].

Note: We must always be aware that numeric values are constant and they do not change until mathematical operations are performed. Also, we must be aware that \[B.C.E\] which means Before Common Era is same as the \[B.C\] i.e. Before Christ.
