The smallest positive integer is-

Hint: In this question we will use the concept of an integer that is an integer can be positive, negative, or zero but cannot be in fraction. As we know that positive integers are all whole numbers greater than zero.

Complete step by step solution:
In this question, we will first discuss the integers.
As we know that an integer is defined as a number that cannot be written in the fractional component. The integers are whole numbers and round numbers. The integers can be positive, negative, or zero but cannot be a fraction. It is used in mathematics to perform various operations like addition, subtraction, multiplication, division, etc. Integers can be positive or negative. Integers can be plotted on a number line. On a number line, positive integers are the numbers to the right from zero and the negative numbers are from the left of zero.
The symbol Z is used to represent integers. The set of whole numbers and the set of natural numbers are called integers.
Positive integers are also a part of a larger group of numbers. Positive integers are used in basic calculations not only in mathematics but also in various fields. Positive integers are all the whole numbers greater than zero such as $1,2,3,4......$. Negative integers are $ - 1, - 2, - 3, - 4......$.
We don’t consider zero as a positive integer as it is neither positive nor negative. Zero cannot be a positive integer as it is neither positive nor negative, so the smallest positive integer is $1$ as it is the first positive natural number.

Note: As we know that natural numbers are those which start from one while the whole numbers start from zero. In solving these types of questions make sure that positive integers are the numbers to the right from zero not with zero as zero is neither positive nor negative.
