How to Learn Square from 40 to 60

Everyone knows the squares till 15 but somehow we are not able to collect square after that which impact directly on speed. So, I am sharing a strategy how you can learn those squares quickly and can apply in calculation in no time.

01 = 01	11 = 121
02 = 04	12 = 144
03 = 09	13 = 169
04 = 16	14 = 196
05 = 25	15 = 225
06 = 36	16 =  256
07 = 49	17 = 289
08 = 64	18 = 324
09 = 81	19 = 361
10 = 100	20 = 400

So, now let us have a look on squares from 20 to 30. The squares below runs in a complementary square. Have a look:-

21 = 441, 29 = 841

22 = 484, 28 = 784

23 = 529, 27 = 729

24 = 576, 26 = 676

Above table shows the square till 20 while below table shows the squares from 40 to 60.

Step 1: Start the counting as shown below:

40 =1600	51 = 26
41 = 16	52 = 27
42 = 17	53 = 28
43 = 18	54 = 29
44 = 19	55 = 30
45 = 20	56 =  31
46 = 21	57 = 32
47 = 22	58 = 33
48 = 23	59 = 34
49 = 24
50 = 2500

Step 2: Then start with 41 and write down the square in reverse order.

40 =1600	51 = 26
41 = 1681	52 = 27
42 = 1764	53 = 28
43 = 1849	54 = 29
44 = 1936	55 = 30
45 = 2025	56 =  31
46 = 2116	57 = 32
47 = 2209	58 = 33
48 = 2304	59 = 34
49 = 2401
50 = 2500

Step 3: Now write the square from top to bottom in a increasing order from 51 to 59 and thats it.

40 =1600	51 = 2601
41 = 1681	52 = 2704
42 = 1764	53 = 2809
43 = 1849	54 = 2916
44 = 1936	55 = 3025
45 = 2025	56 =  3136
46 = 2116	57 = 3249
47 = 2209	58 = 3364
48 = 2304	59 = 3481
49 = 2401
50 = 2500

Have Fun and Enjoy Studies.
