= 250 - (100 - 4) (**here, instead of subtracting 96 from 250, we are just subtracting 100 from 250 and then adding 4) **
= 250 - 100 + 4 (**Why adding? because the actual amount we have to subtract from 250 is 96. but we are subtracting 100.
That means, we are subtracting 4 numbers more than we actually deserve.
so our 250 will feel bad. so we should add that 4 to it:)**
= 150 + 4

= 154

250 - 196

= 250 - (200 - 4)

= 250 - 200 + 4 (**here also same. In order to subtract 196, we subtract 200 and adding 4)**
= 50 + 4

= 54

**Note : We can use this logic for any number. According to our convenience.**

**Lets see, **

216 - 61 (**Here i found it difficult to subtract 61 from 216)**

= 216 - (100 - 39) (**So i just decided to subtract 100 to it and later will subtract the extra 39)**

= 216 - 100 + 39 (**Hey, see here. How about writing this 39 as 40 -1 ?)**

= 116 + (40 - 1) **(dont be confused. just practice this method and you will come to know how easy and efficient method it is :)**

= 156 - 1

= 155
