MATRIX ARITHMETIC
Guest_
These numerals may say something

4 3 8 四 海 三 山 八 重 天
9 5 1 九 牛 五 虎 一 斉 眠
2 7 6 二 妹 七 姐 遊 六 國

周 圍 十 五 月 團 圓

But try this ...

Draw a square and divide it into 25 quadrants. Fill each quadrant with a numeral using numbers 1 – 25 to obtain an all round total of 65 at each vertical line, each horizontal line and the 2 diagonal lines. Each number may be used only once. All 25 numerals must be used.

Good luck.

Hello Kathy ...

You are getting to it! But still a long way.

Here, take this hint!

Clue 1 : Why is the all-round total 65? It is because number 13 is the middle number of numerals 1~25. And if you multiply 13 by 5, you get 65.

Clue 2 : Number 13, being the middle number, MUST be placed in the centre of the 25 squares.

Give it some further thoughts.

Cheers.

Btw, it's hard to log in here due to the damages done to the fibre optics during the earthquake.

Thanks for the info, 123.
Hope your baby will grow stronger and stronger day by day.
(Imho, "good wine needs no bush"; just let him/her grow in a natural and healthy way. Boosting medicine will only be needed when he or she is in an unpleasant state.)

Hi Futari

Not throwing a challenge at you. I know you are non-stoppable!

How about 1 ~ 81 with the same all round total?

Members will appreciate your talents if you share your knowledge.
