Addition with Carrying

Addition With Carrying

Let us solve an example with 2 digits number Add 45 to 86 Add the ones column digits 5+6 we get 11, write 1 under the ones column, and carry the another 1 to tens column, next add the tens column digits and the carried number i.e., 4+8+1 we get 13. Therefore the result is 131. Let us try to ... Read More »

Subtraction Of Whole Numbers On Number Line

Subtraction Of Whole Numbers On Number Line

Let us learn how to subtract the whole numbers by the help of a number line. First draw a number line as shown in the figure below. Let us consider an example 7-5 and try to subtract them on number line. On the number line when you are subtracting 5 from 7, you are moving towards the left side. First, ... Read More »

Absolute Value Comparison

Absolute Value Comparison

By comparing absolute value of integers, using the greater than(>), less than( | -27 |. Example 4. The absolute value of -46 is 46, and -96 is 96. So 46 is less than 96. Therefore the result is | -46 | < | -96 |. Example 5. By solving -25+5 we get -20, coming to 15-25 we get -10. The ... Read More »

Absolute Values Example -1

Absolute Values Ex-1

Let us solve few examples : The absolute value of | 8 – 7 | To solve the example, subtracting 7 from 8, we get 1, then the absolute value of |1| is 1. Therefore the result for | 8 – 7| is 1. The absolute value of | 1 – 4 | By subtracting -4 from 1, we get ... Read More »

Absolute Value

Absolute Value

Absolute value is the distance of an integer on the number line from zero. The absolute values are not having the negative values and symbol of the absolute is represented by two vertical lines. Let us try to solve an example Find absolute value of -5 The distance from 0 to -5 is 5 units. Therefore absolute value of -5 ... Read More »

Prime And Composite Numbers

Prime and Composite numbers

Prime number is an integer that can be divided by 1 and itself and the result is always an integer number. There are infinite number of prime numbers such as 2, 3, 5, 7, 11, 13, 17,19 and so on. Composite number is a whole number and which is having the two or more factors. Example of composite numbers are ... Read More »

Multiplication Of More Than Two Negative Integers


In this chapter we are going to learn how to multiply more than two negative integers. Let us solve few examples : -6 x -3 There are two negative integers -6 and -3, so here 3 times of 6 is 18 and signs are same, so the result must be in positive. Therefore the result for -6 x -3 is ... Read More »

Multiplication Of A Positive And A Negative Integer


We are going to learn in this chapter is multiplication of a positive and a negative integer. As we know that two opposit signs always gives a negative result. Let us consider few more examples : 2 x -5 -6 x 8 In the first example, multiply a positive integer with a negative integer, i.e., 2 x -5. So here ... Read More »

Multiplication Of Two Negative Numbers


Already we have discussed earlier, which is two opposite sign will give the result in negative and if two signs are same, then it will get the result in positive. Now, let us solve few examples -4 x -6 By multiplication table, we can say that 4 times of 6 is 24 and here we have the same signs, i.e., ... Read More »

Division of Integers

Division Of Integers

In this lesson will teach you how to divide the integers with few examples. Remember when we have two opposite signs, then the result should be in negative, otherwise the result is positive. Let us try to solve few examples : 27/3 -14/2 When we are solving the examples remember the multiplication table and now let us consider a first ... Read More »
