  2. INTRODUCTION • Whole number is a serial number starting from 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10,…... • Whole numbers are the basis of most of the mathematical ideas • Mastery of basic skills can help students learn other topics. Fraction & Decimal is not a whole number!

  3. 1.1.1PLACE VALUE • Each digit in a number has a place value and value of a particular digit • Number above is 493 • Have three digits • Digit 3 is in place "sa". Value 3 indicates that there are three "a" • Digit 9 is located at "twenty". Value of 9 indicates that there are 9 "twenty" • Digit 4 is in place "hundred". Value of 4 indicates that there are four "hundred"

  4. Write whole numbers in words • Thirty-one • Three hundred and seventy-five • Two thousand four hundred and eighteen

  5. Write whole numbers in figures • Fifty-six • 56 • Seven ratuh twenty-three • 723 • Five thousand six hundred and twenty-seven • 5627

  6. rounding • Rounding is used to obtain the expected value. The expected value is the nearest value. • A number can be rounded to a specific place value in accordance with the following rounding rules. • if the digit is 5 or more, add 1 to the digit in the place to be rounded up and replace the other digits to the right of 0. •   if the digit is less than 5, keep the digit in the place to be rounded up and replace the other digits to the right of the empty

  7. > More than < Less than > example < Round 457828 to the nearest hundred 457828 2<5 , keep the digits 8 and replace all digits to the right of 0 Place value is hundreds answer : 457800

  8. > example < > More than < Less than Round 4279 to the nearest fifty 4279 9>5 , add 1 to the digit 7 and replace all digits to the right of 0 Value place is twenty answer : 4280

  9. ADDITION AND SUBTRACTION ADDItion Addition is the process of finding the sum of two or more numbers. The steps involved in the addition of whole numbers: Arrange the numbers vertically according to the place. Add the digits in descending order, a, twenty, hundred and beyond. Step work from right to left.

  10. EXAMPLE 1 : Solve 526 + 621 = ? EXAMPLE 2 : Solve 5327 + 56 = ? EXAMPLE 3 : Solve 1123 +5610 = ? 526 + 621 1147 1183 + 5670 6853 5327 + 56 5383

  11. ADDITION AND SUBTRACTION SUBTRACTION • Subtraction is the process of finding the difference between the two to find the remainder when a smaller number subtracted from the larger number. • Example: subtract 3 from 9, 9 - 3 = 6. • The steps involved in subtraction of the whole number is the same the steps that need to be taken to increase.

  12. EXAMPLE 1 : Solve 765-123 = ? EXAMPLE 2 : Solve 4561 – 381 = ? EXAMPLE 3 : Solve 8534 -5730 = ? 765 - 123 642 8534 - 5730 2804 4521 - 381 4140

  13. MULTIPLICATION AND DIVISION multiplication • Multiplication is repeated addition process. • Steps to perform multiplication: = Round numbers sorted by the place. = Multiply by a, twenty and beyond. • The product of a whole number by the number zero is equal to zero (3 x 0 = 0) • The product of a whole number of one, corresponding to the number itself (9 x 1 = 9)

  14. EXAMPLE : Solve 318 x 34 = ? 3 1 8 X 3 4 1 2 7 2 9 5 4 1 0 8 1 2

  15. MULTIPLICATION AND DIVISION DIVISION • Division is the equal sharing operations. • When 0 divided by any number, the result is either 0 (0 ÷ 5 = 0). • Division of a number by 0 is worthless. • Steps to do the division: = Round numbers arranged in conventional form. = Begin dividing the value of the greatest.

  16. EXAMPLE : Solve 576 ÷ 18 = ? 3 2 1 8 5 7 6 5 4 3 6 3 6 . .

  17. PRINCIPLES OF CALCULATION • When there is only one operation, a calculation is done from left to right. • Calculation involving the operations' + ' and' - ' only' or 'x' and '÷' only, a calculation is done from left to right. • To make calculations involving brackets and a number of operations, operating in the proper brackets solved first, followed by the 'x' and '÷' and a '+' and '-'. For example, 45 + (2 x 5) - 12 ÷ 4 = 52.
