Subtracting Whole Numbers
Subtracting Whole Numbers
Subtracting whole numbers is the inverse operation of adding whole numbers. Instead of adding two
numbers to get a sum, you are removing one number from another to get a difference First, look at the
following simple simple subtraction problems. The first is 8 - 4 = 4. Thinking about money, you have
8 dollars and you spend 4, you are left with 4. Subtractions with one digit are usually fairly easy.
Things start getting complicated when you have more than one digit and you cannot remove the
number at the bottom from the number on top such as when doing 85 - 8. Study the following
example carefully because the concept of borrowing a ten is illustrated here. Since you could not
remove 8 from 5, you borrowed a ten from 8 tens and add that to 5 to make it 15.
In arithmetic, subtraction is one of the four basic binary operations; it is the inverse of addition,
meaning that if we start with any number and add any number and then subtract the same number we
added, we return to the number we started with. Subtraction is denoted by a minus sign in infix
notation, in contrast to the use of the plus sign for addition. Since subtraction is not a commutative
operator, the two operands are named. are minuend (c) - subtrahend (b) = difference (a). subtraction =
value1 - value2 Subtraction is used to model four related processes. From a given collection, take
away (subtract) a given number of objects. For example, 5 apples minus 2 apples leaves 3 apples.
From a given measurement, take away a quantity measured in the same units.

Compare two like quantities to find the difference between them. For example, the difference between
$800 and $600 is $800 - $600 = $200. Also known as comparative subtraction. To find the distance
between two locations at a fixed distance from starting point.Improper fractions and the whole numbers
are the sub-types of number system. Improper fractions numbers are the type of fractional numbers in
number system.In the above example we can see that the value of numerator is greater then the value of
denominator. This makes it improper fractions. In the fraction there are types of fractions are define......
a) Proper fractions: 5 / 6 in this example we can see that the 5 is a numerator value which is lesser then
the denominator value 6. So this is proper fraction.
b) Improper fractions: 4 / 3 in this example we can see that the value of 4 is a numerator value which is
greater then the value of denominator that is 3. So this can be known as Improper fractions.
c) Mixed fractions: in this type of fractions the whole values are added with the fraction numbers like 2
1/2.
Now we define the whole numbers. Whole numbers are the most basic type of numbers system. In the
type of number system we generally include the number that has the range from 0, 1, 2, 3, 4......and so
on. These are the numbers that are used to form the other types of numbers in the number system. As
like whole number we can also perform the various operations between the whole numbers and
improper fractions. In the case of subtracting the improper fractions with the whole numbers, we need
to follow the some steps:
a) First convert the whole numbers into the fractions.
b) After determining the fraction numbers, calculate the LCM.
c) Then equalize the denominators of both numbers.
d) At last perform the subtraction between the given fractional numbers.
e) In the end there is a any need then simplify the obtained fraction.
