### Square Any Two Digit Number in Seconds

For a squaring a number which ends with 5, follow link below:

For any other two digit number follow steps below:
1. First look for the nearest 10 boundary of number (like for 48 its 50)
2. As we went two up so write a number two below this number. ( number two below 48 is 46)
3. Now multiply 46 to 50. (46 * 50 = 2300). This is our answer 1.
4. As 48 is 2 number away from 50 so find square of 2 = 4. This is our answer 2.
Follow examples below to understand it better:

Eg. 1:

(24)2
Step -1 => 20 is nearest number.
Step -2 => As we move down by 4 numbers so 4 number above 24 is 28.
Step -3 => 28 * 20 = 560 (Answer 1)
Step -4 => As 24 is 4 numbers away from 20. So square of 4 = 16. (Answer 2).
Step -5 =>Now Answer 1 + Answer 2 = 560 + 16 = 574.
Hence (24)2 = 574. (Ans)

Eg. 2:

(57)2
Step -1 => 60 is nearest number.
Step -2 => As we move up by 3 numbers so 3 number below 57 is 54.
Step -3 => 54 * 60 = 3240 (Answer 1)
Step -4 => As 57 is 3 numbers away from 60. So square of 3 = 9. (Answer 2).
Step -5 =>Now Answer 1 + Answer 2 = 3240 + 9 = 3249
Hence (57)2 = 3249. (Ans)

### Try it yourself:

• (27)2 =
• (52)2
• (63)2
• (74)2 =
• (88)2
