ADDITION OF ONE

ADDITION OF ‘ONE’

If we add One ‘1’ with any number, then the result of the addition will be one number excess than the given number. Suppose if we want to add one ‘1’ with any number ‘N’ then the result of addition or summation will be N + 1 = ( N + 1). There are some example are given below for your better understanding –

Example.1)   6 + 1 =  7

                           7

                      +   1

                     ----------

                           8             (Ans.)

Example.2)    19 + 1  =  20

                           19

                       +   1

                      ----------

                           20              (Ans.)              

Example.3)    24 + 1  =  25

                           24

                       +   1

                     ------------

                           25                 (Ans.)

Example.4)    99 + 1  =  100

                           99

                       +   1

                    -------------

                          100               (Ans.)

Example.5)    150 + 1  =  151

                          150

                       +    1

                    --------------

                          151                (Ans.)

Now for better understanding we will add one ‘1’ with any object. Addition of one ‘1’ with any object or particle means whatever the object has been given that number will be added with one another same object or article, and obtained number would be one number more than given object or article .

In above picture we can observe that, 7 no.s tiger has been added with one tiger and now the obtained or the result of addition would be 7 + 1 =  8 tigers (just next number of 7).

In above picture we can observe that, 10 no.s ducks has been added with one duck and now the obtained or the result of addition would be 10 + 1 =  11 ducks (just next number of 10).

In above picture we can observe that, 5 no.s giraffe has been added with one giraffe and now the obtained or the result of addition would be 5 + 1 =  6 giraffe (just next number of 5).

In above picture we can observe that, 6 no.s puppies has been added with one puppy and now the obtained or the result of addition would be 6 + 1 =  7 puppies (just next number of 6).
