Mathematics is said to be the study of patterns scattered around us, and the fun in math is to explore these patterns with the help of numbers. Arithmetic, in general, has classified numbers into various categories depending on their properties and the manner in which they represent things. Types of numbers include integers, real numbers, natural or counting numbers, real numbers, complex numbers.
There are different types of numbers that can be given to you depending on what’s being counted and how many digits are used to represent it. In this blog post, we’ll go over some commonly used numerals in arithmetic and discuss why they’re used as well as their varying functions within subtraction, multiplication, division, and addition.
Integers are whole numbers that do not have a fractional component. Integers can be positive (e.g., 1, 3) or negative (e.g., -3, -5). This means that decimals and fractions are not integers. For example, 4 is an integer because the number is whole. In mathematics, the set of integers is often called “Z”. The word integer is also used in algebraic number theory to refer to components of an algebraic number field that are integral over Z.
Integers can be said to be a set of number zero, the positive numbers 1, 2, 3 as well as their negatives like -1, -2, -3, and so on. A number line separates integers into two distinct categories: the positive integers, which are to the right of zero; and the negative integers, which are to the left of zero. So these can be called positive and negative integers. The set of integers is a subset of rational numbers, and rational numbers are a subset of real numbers. Integers are also infinite just like the natural numbers tend to extend to infinity. All rational numbers, such as the integer 2 and the fraction 2/3, are included in the real numbers, as are all irrational numbers, such as the square root of 2 (an irrational algebraic number). The real transcendental numbers, such as ‘pi,’ are included in the irrationals. Since real numbers are used in the measurement of quite a lot of quantities, hence their usage is in measuring distance, mass, energy etc.
Natural numbers such as 1, 2, 3, 4, and so on are used to count. Counting numbers and zero are included in whole numbers. Fractions that are expressed as terminated or repeated decimal are non-integers. Irrational numbers are divided into two categories: algebraic and transcendental. Algebraic ones are those with the square root of 2 as the algebraic equation’s roots. Transcendental numbers, which are represented by pi and e, where pi is a trigonometric function and e is an exponential function, are the other category of numbers. Irrational numbers can appear in a variety of forms. The decimal portion of irrational numbers never ends and never repeats itself, making them non-repeating and non-terminating. The value of pi is the most frequent irrational number.
When it comes to fractions, ratios, and equations, these distinct sorts of numbers may behave in somewhat different ways. Another type of categorization is ordinal numbers, which are defined as first, second, third, and so on and denote the position or order of something in relation to other numbers.
Math worksheets centered on numbers are an excellent way to reinforce these ideas of numbers, and there are plenty of them available online. Cuemath is an example of an online platform where students may access a range of interactive and interesting worksheets for daily practice. These are also divided into groups based on the kids’ age and comprehension levels.
