Number Sense and Numeration   Introduction Everything is counted by numbers. Numbers are the symbolic representation of counted objects. Categorized of numbers are basically dependent on their factors and divisibility.   Types of Number Natural Numbers Counting numbers are known as natural numbers. For example, natural numbers (N) = {1, 2, 3, 4, 5 ?.. infinite}   Whole Numbers Counting numbers including 0 are known as whole numbers. For example, whole numbers (W) = {0, 1, 2, 3, 4?. infinite}   Prime Numbers Those numbers having two factors 1 and the number itself are called prime numbers. For example, prime numbers (P) = {2, 3, 5, 7, 11, 13 etc.}   Twin Numbers Two numbers with difference of 2 are called twin primes. For example: {3, 5}, {5, 7}, {11, 13} etc.   Note: 2 is even prime number.   Composite Numbers Numbers having more than two factors, 1 and the number itself, are called composite numbers. For example: {4, 6, 8, 9, 10 etc.}   Even Number more...

Addition and Subtraction   Addition Addition is the combination of two or more quantities in a single quantity. This is one of the four basic arithmetic operations. Symbol for addition is +.   Addition of Four Digits Numbers without Carry Over Following are the steps used in this type of addition. For example: addition of 4784 and 3214. Step 1: Add ones 4 + 4 = 8. Write 8 under ones column. Step 2: Add tens 8 + 1 = 9. Write 9 under tens column. Step 3: Add hundreds 7 + 2 = 9. Write 9 under hundreds column. Step 4: Add thousands 4 + 3 = 7. Write 7 under thousands column.             Hence, addition of 4784 + 3214 = 7998.   Addition of Four Digit Numbers with Carry Over Following are the steps used in this type of addition. For example addition of 7569 and 5984. Step 1: Add ones, 9 + 4 = 13 = 1 tens + 3 ones. Write 3 under ones column and carry one tens to the tens column. Step 2: Add tens, 6 + 8 + 1 (carry over) = 15 tens = 1 hundred + 5 tens.             Write 5 under tens column and carry 1 hundred to the hundreds column. Step 3: 1 thousand 5+9+1 (carry over) =15 hundreds.             Write 5 under hundreds column and carry 1 thousand to the thousand column Step more...

  Multiplication and Division   Multiplication Multiplication means repeated addition. The symbol for the notation of multiplication is ''.   Multiplication of Three Digit Numbers with One Digit Number Following are the steps for multiplication of three digit number with one digit number For example, 236  4 Step 1: Multiplication always start with ones. Step 2: Multiply ones 6  4 = 24. 2 tens and 4 ones. Write 4 under ones column and carry 2 tens to the tens column. Step 3: Multiply the tens 4 3 = 12 + 2 (carry over) - 14 tens = 1    hundreds 4 tens. Write 4 under tens column and carry 1 hundred to the hundreds column. Step 4: Multiply the hundreds 4  2 = 8 + 1 (carry over) = 9 hundreds. Write 9 under- hundreds column.                             Multiplication of Four Digit Numbers with Two Digit Numbers Following are the steps for multiplication of four digit numbers with two digit numbers: For example, 4526  56 Step 1: Arrange the multiplicand and multiplier more...

Fraction  Introduction The Latin name of fraction is fractus. It means broken. Fractions are always in ratio form. It has two parts, upper and lower part. The upper part is called numerator and lower part is denominator.   Fractions in its Lowest Term The lowest term of a fraction is obtained by dividing numerator and denominator with common divisor. The lowest form of the fraction  \[\frac{6}{9}\,\,is\,\frac{2}{3}\] . The lowest term of the fraction \[\frac{6}{9}\] is obtained by dividing the numerator and denominator with a common divisor 3.  

•            Example

What is lowest term of the fraction\[\frac{\mathbf{45}}{\mathbf{65}}\]?             (a) \[\frac{9}{13}\]                                                         (b) \[\frac{2}{3}\]             (c) \[\frac{5}{9}\]                                                                       (d) All the above             (e) None of these Ans.     (a)             Explanation: Common divisor of 45 and 65 is 5. Therefore, dividing 45 and 65 by 5, we get \[\frac{9}{13}\]  

•           Example

            Find the simplest form of the shaded parts of the figures in fraction given below:                         (a) \[\frac{3}{8}\]                                                                       (b) \[\frac{1}{2}\]                        (c) \[\frac{1}{5}\]                                                                       (d) All the above             (e) None of these Ans.     (b) more...
