Question

Write the opposite of the following:

$326BC$

Answer 1

Let's find the opposite of $326BC$:

In the calendar system, $BC$ stands for ‘Before Christ’. It is used to label or number years before the year in which Jesus Christ was born. Similarly, $AD$stands for ‘Anno Domini’. It refers to the years after Jesus Christ was born.

So, mathematically, $BC$ and $AD$ can be seen as two opposite directions on the number line. The opposite of an year in $BC$ will be the same year in $AD$.

Hence, the opposite of $326BC$ is $326AD$.
