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

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.

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.

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)

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.

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.
