BEFORE-AFTER-BETWEEN

**Before, After, Between –**

**We have already learned the concept of before, after, and
between in the previous classes. Here we shall revise what comes before and
after any number.**

**There are some examples are given below for your better
understanding – **

**Example.1) Number 455**

**To find the before number of a given number we have to subtract
1 from a given number and to find the after number we have to add 1 with the given
number. So, the number before 455 is = 455 – 1 = 454**

**And the number after 455 is = 455 + 1 = 456**

**So, the numbers before and after 455 are 454 & 456
respectively. (Ans.)**

**Example.2) Number 237**

**To find the before number of a given number we have to subtract
1 from the given number and to find the after number we have to add 1 with the given
number. So, the number before 237 is = 237 – 1 = 236**

**And the number after 237 is = 237 + 1 = 238**

**So, the numbers before and after 237 are 236 & 238
respectively. (Ans.)**

**Example.3) Number 753**

**To find the before number of a given number we have to subtract
1 from a given number and to find the after number we have to add 1 with the given
number. So, the number before 753 is = 753 – 1 = 752**

**And the number after 753 is = 753 + 1 = 754**

**So, the numbers before and after 753 are 752 & 754
respectively. (Ans.)**

**Example.4) Number 356**

**To find the before number of a given number we have to subtract
1 from a given number and to find the after number we have to add 1 with the given
number. So, the number before 356 is = 356 – 1 = 355**

**And the number after 356 is = 356 + 1 = 357**

**So, the numbers before and after 356 are 355 & 357
respectively. (Ans.)**

**Example.5) Number 486**

**To find the before number of a given number we have to subtract
1 from a given number and to find the after number we have to add 1 with the given
number. So, the number before 486 is = 486 – 1 = 485**

**And the number after 486 is = 486 + 1 = 487**

**So, the numbers before and after 486 are 485 & 487
respectively. (Ans.)**

**Example.6) 254, 565, 328, 549, 873, 984, 365, 751, 866, 379,
816 are some numbers which are given
below in the table, find before and after number of the given number**
