Squaring a 2-digit number which is between 25-50

__Find the Square of 43__
**Step-1**: find the difference(d) with 50==>**43 is 7 less than 50** so d=7
**Step-2**:find the square of difference(d) ==> **Square of 7 is 49**,so it is our 1st part.
**Step-3**: Now find difference of 25 and 'd' ==>**25-7=18,** it is second part.
So our answer is **1849**
**Example:Find The Square of 38**
**Step 1:** 38 is12 less than 50 so d=12
**Step 2**:Square of 12 is 144,but we have to write it in **2 digit means 44** and 1 carry
**Step-3:**25-12=13 and 1 carry ==>13+1=14
** **So our Answer is** 1444**
