Addition of Large Numbers Addition is one of the four basic operations of arithmetic, the others being subtraction, multiplication and division. Till now we have read addition of numbers which are very small and could be added just by counting. For example, Ron had 5 oranges and Sam gave him 7 oranges more. Total Oranges […]
MATHEMATICAL OPERATIONS We use arithmetic operations in our everyday life. Suppose you have chocolates and you have to distribute them among your friends equally. How will you do it? Simply just count the friends and divide it equally. Just like when you go out for shopping and you pay. How do you know that the […]
Large Numbers How far is moon from earth? What is the speed of light? How many cells are there in the human body? The answers to these questions are numbers that go way beyond 10’s or 100’s. This chapter gives us an idea about numbers beyond 1000. In this chapter, we learn about Read and […]
Order Relations Successor & Predecessor A number that comes just after “a given” number is called its successor. It is one more than the given number. A number that comes just before “a given” number is called its predecessor. It is one less than the given number. Examples: Comparison of Numbers When two numbers have different number of […]
Expanded Form: International Place Value System The expanded form varies in the Indian and International structure as per their defined period. We just learned how to expand a number per the Indian Place Value System, now let us go through some examples to learn about the International Place Value System. The key point of difference […]
Expanded Form A number when expressed with its place value denotes its expanded form. Suppose we write a number 619, here we actually mean that we have a total of 600 + 10 + 9. This expansion shows the value of each of its digit and hence represents the expanded form. The expanded form varies […]
Introduction: Place Value System, India and International According to our number system, the value of a digitdepends upon the place it holds in the number. The TRUE and ACTUAL value of a number depends on two factors: Face value of a digit in a number is the digit itself Place value of a digit in a number depends upon […]
The Indian Place Value System Using the same concepts as we had learned in the introduction, the Indian Place Value System is also a Base -10 number system, with following key rules: We start grouping the number from the right, first in group of 3 and then further in groups of 2. Starting from the right, the first period is ones, consisting of three place values […]
The International Place Value System In this system, we start grouping the number from right in group of 3 called period. Starting from the right, the first period is ones, consisting of three place values i.e. ones, tens and hundreds. The next period is thousands, consisting of three places i.e. thousands, ten-thousands and […]
Prime Factorization When we express a composite number as a product of prime numbers, it is called prime factorization. The set of prime numbers are called the prime factors of the given number. Example-Let us take a number 24. Factors of 24 = 1, 2, 3, 4, 6, 8, 12 and 24. Out of these factors, […]
