Question

The sum of predecessor and successor of 1000 is ?

Answer 1

Hint: There are numbers called natural numbers. These numbers start from 1 and go up to infinity. As we go on adding up one in each number we will form a series 1,2,3,4,…so on. The numbers go on from single digit to double digit and so on. In the question we are given 1000 which is a four-digit number.

Complete step by step answer:
As we discussed the number of digits are increased along with the digits in the numbers. We have provided a four-digit number 1000 in our question. First, we need to understand the question and terms given in the question. There are two terms in the question: predecessor and successor.

Predecessor is the number which comes before the given number or we can say that the deducting one from the number 1000.
\[1000{\text{ }} - {\text{ }}1\] we will get 999.
Successor is the number which comes after the given number or we can say that if we add one in the number given we will get its successor.
\[1000{\text{ }} + {\text{ }}1\] we will get 1001.
We have asked to give the sum of these two numbers. Sum is the addition of two numbers.We have obtained two numbers as 1001, 999.
\[1001 + 999{\text{ }} = 2000\]

Hence, the sum of the predecessor and successor of the number 1000 is 2000.

Note:Number system is the system which is designed to represent the numbers. It is a mathematical representation of numbers and sets. It helps us in providing the unique representation and better understanding of the given set of numbers. Number systems can be given as follows:
-Decimal number system (Base-10): Generally used
-Binary number system (Base-2): It is also known as the language of computers.
-Octal number system (Base-8): Construction of values in binary system
