# arithmetic – Squares inside a sq.

Solution 1 with 2 as middle

9 4 8
6 2 5
1 3 7

13 squares { 1,4, 9, 16, 25, 36, 49, 64, 169, 324, 625, 729, 961 }

Strategy:

I first write down the all 3 digits squares then I search for the three
digit squares with a most stable middle. means a most of three digits
squares with frequent middle quantity. I discovered there are 4 a majority of these
squares {324, 625, 529, 729} the place the frequent middle is 2. so I made 2
is my middle quantity and write down all the three digits squares. then I
tried to cowl the opposite 3 digits squares by rearranging them. then
lastly I search for all 2 digit squares and be capable to get them largely
besides 81. Also, yet one more factor {169 and 961} can be a great combo so
do not miss it. in the event you see the three digit sq. checklist beneath that we are able to
use, we are able to clearly see that 2 makes essentially the most stable middle so essentially the most
stable answer, after it 6 and eight may give a greater end result.

Possible 3 digit squares we are able to use with stable facilities.

1. {324, 529, 625, 729} we are able to both use 529 or 729 so 3 left

2. {169, 361, 961 } {we are able to both use 361 or 961 so 2 left}

3. {289, 784 } {we are able to use each}

4. {841}{196}{256}{576} {4,9,5,7 with middle we’ll get only one sq.}
as you may see above we are able to use 3 of three digit sq. with 2 as middle that may give us greatest answer. 729 is giving higher answer than 529 as a result of with 729 we’re getting benefit of utilizing yet one more 3 digit sq. 625 which isn’t doable with 529 as a result of we are able to both use 529 or 625.

Solution 2 with 2 as middle

5 7 8
3 2 4
1 6 9
identical technique 12 squares { 1,4, 9, 16, 25, 36, 49, 64, 169, 324, 529,
961 }

Solution 3 with 8 as middle

2 7 1
5 8 6
3 4 9

Another 12 squares{ 1,4, 9, 16, 25, 49, 64, 81,169, 196, 289, 784 }

Solution 4 as 6 as the middle.

1 5 7
8 6 2
3 4 9

12 squares identical technique { 1 ,4, 9, 16, 25, 49, 64, 81,169, 729, 961 }
