In addition to the revision notes for Number Sets, Positive and Negative Numbers and Number Lines on this page, you can also access the following Arithmetic learning resources for Number Sets, Positive and Negative Numbers and Number LinesIn these revision notes for Number Sets, Positive and Negative Numbers and Number Lines, we cover the following key points:What is the definition of a set in general? What is a number set? What are natural numbers? What common feature do they share? What are whole numbers? Where do they differ from natural numbers? What are integers? Do they have a beginningend? What are rational numbers? What is the name we more commonly refer to them as? What are irrational numbers? Do they have anything in common with rational numbers? How do we know whether a given number is rational or irrational? What are real numbers? What is a number line? In what direction do values increase in a number line? Sets are groups or collections of items which have common properties.The common feature all number sets share is that all of them contain not just numbers, but these numbers are related between them through a formula or rule. Depending on the situation involved, we have the following sets of numbers:Natural Numbers, N. This is the oldest set of numbers that includes numbers like 1, 2, 3, 4, .... etc. We can write the set of natural numbers N in a list form likeN = 1, 2, 3, 4, 5, 6, 7, ....The common feature, in this case, is that natural numbers represent whole and positive values. Natural numbers have a beginning (the number 1) but no end; they can extend to infinity.Whole Numbers, W are similar to natural numbers but also includes zero. This set also has a beginning (the number zero) and no end. Hence, when this new set is expressed in list form, it becomesW = 0, 1, 2, 3, ....Integers, Z includes both positive and negative whole numbers and a zero. It has neither beginning, nor end. When expressed in list form, the set of integers is written asZ = ...,-3, -2, -1, 0, 1, 2, 3, ....Rational Numbers, Q (i.e. numbers written as ratios) represent sets of numbers which usually represent part of the whole. They are otherwise known as fractions. The distinctive feature of rational numbers is that the numerator of fraction must be an integer while the denominator a natural number.Irrational Numbers, I are those numbers that cannot be expressed as fractions. A number can either be rational or irrational but not both.The set of Real numbers, R includes all the above sets. This set includes both the whole and not whole numbers.Numbers can be shown in a number line where the number zero is taken as origin. Positive numbers are usually placed on the right of origin while negative numbers on its left.Enjoy the Number Sets, Positive and Negative Numbers and Number Lines revision notes?

It starts from zero, and the numbers increase when you move from zero to the right and decrease from zero to the left. Shifting to right or left indicates the negative or positive directions.Meet the Best Maths Tutor for Free>>The number line is used for addition and subtraction purposes in mathematics. It has two sides, a Negative Number Line and Positive Number Line. Both sides can be extended infinitely in a horizontal manner. Also, the ends of number lines are indicated by arrows.Negative Number LineThe left side of a number line is called a negative number line. It increases in number but with a negative sign, and the negative sign means the value of the number or integer is decreasing. The left side of the number lines is used for subtraction and addition purposes mostly.Numbers on the left side of zero are always smaller than the numbers on the right side.Example:To add numbers on the negative number line, you must know how to use addition and subtraction signs. For adding (-1) and (-4), look for -1 number on the negative number lines and move 4 steps in the left direction. The number you will get after moving four steps forward will be the answer.The right side of a number line is called the positive number line. It increases in numbers too, but they all are whole numbers. The right side of the number lines is used for the addition and multiplication of numbers mostly.Example:To add (1) and (7) on a number line. Look for number 1 and then move 7 steps forward in the right direction, drawing a line in the horizontal direction. The number you will get after moving seven steps from point 1 will be the answer.Hence, the answer is 8.Number lines with negative numbers and positive numbers are used to teach children the basic concepts of addition and subtraction in Mathematics. It is also used for multiplication by skipping count. Solving equations of negative numbers of a number line is tricky as positive or negative signs are used.Apparently, number lines seem like an essential method of teaching kids the concepts of addition, subtraction, and multiplication, but they can be used in numerous other ways. People use the negative number line and positive number lines to calculate and measure details. These lines show the significant increase and decrease of values.Brush up on your mathematical skills and attain the highest grades with our experienced math tutors. Take a free trial now.
