Question

Write the predecessor of 10000.

Answer 1

Hint- Here, we will be using the definition of predecessor of a number.

As we know, the predecessor of a number is the number which comes exactly before that number.
Predecessors of any given number can be simply calculated by subtracting 1 from the given number. So, the predecessor of any number $a$ is given by $\left(a-1\right)$.
So, the predecessor of 10000 is $\left(10000-1\right)=9999$ i.e., the predecessor of 10000 is 9999.

Note- In these types of problems, we subtract one from the given number in order to find the predecessor of the given number.
