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!
hundred twenty a
4 9 3
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"
•Each digit in a number has a place value and value of a particular digit
hundred twenty a
3 7 5
Three hundred and seventy-five
thousand hundred twenty a

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
Round 457828 to the nearest hundred
457828
Place value is hundreds
2<5 , keep the digits 8 and replace all digits
to the right of 0
answer :457800
> More than< Less than
Round 4279 to the nearest fifty
4279
Value place is twenty
9>5 , add 1 to the digit 7 and replace all digits to the right of 0
answer :4280
> More than< Less than
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:
i. Arrange the numbers vertically according to
the place.
i. Add the digits in descending order, a, twenty, hundred and beyond.
ii. Step work from right to left.
EXAMPLE 1 :Solve 526 + 621 = ?
EXAMPLE 2 :Solve 5327 + 56 = ?
EXAMPLE 3 :Solve 1123 +5610 = ?526
+ 6211147
5327+ 56
5383
1183+ 5670
6853
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.
ADDITION AND SUBTRACTION
EXAMPLE 1 :Solve 765-123 = ?
EXAMPLE 2 :Solve 4561 – 381 = ?
EXAMPLE 3 :Solve 8534 -5730 = ?
765- 123
642
4521- 381
4140
8534- 5730

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)
EXAMPLE :Solve 318 x 34 = ?
3 1 8X 3 4
1 2 7 29 5 4
1 0 8 1 2
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.
MULTIPLICATION AND DIVISION
EXAMPLE :Solve 576 ÷ 18 = ?
3 21 8 5 7 6
5 43 63 6. .
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.
