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

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

Value place is twenty

9>5 , add 1 to the digit 7 and replace all digits to the right of 0

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

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.
