Place numbers into the puzzle cells in such a way that each row and column
contains each of the digits from 1 up to the size of the puzzle(5).Like a Sudoku
puzzle, no number is repeated in any row or column. Each bold- outlined group
of cells contains a hint consisting of a number and one of the mathematical
symbols +, x, -, /. The number is the result of applying the mathematical
operation represented by the symbol to the digits contained within the
domain. The solution to each puzzle is arrived at logically and is unique.

A E F H R T 2 0 3 1 0 0
5! X 2 + 4! X 0 + 3! X 3 + 2! X 1 + 1! X 0 + 0! X 0 = 260 +1 =261
2. How to find fourth vertex in //gm. [ If A (x1,y1) , B ( x2,y2) , C (x3,y3) are three vertices ]
then D ( x1+x3 – x2, y1+y3 – y2) .
3. How to multiply in easy manner/way: 107 x 106 ( just over 100)
107 + 6/106 + 7 = 113 & 7 x 6 = 42 so 107 x 106 = 11342, find 103 x 105 = ? & 108 x 107 =?
Now see another multiplication : 112 x 115 = 12880 [112+15 =127 & 12 x15 = 180 ]
4. When first figures are the same and last figures add up to 10 :
32 x 38 = 1216 [ 2 x8 = 16 & 3 x 4 = 12 ]
98 x 92 = 9016 [ 9 x 10 = 90 & 8 x 2 = 16 ]
5. Multiply a number by 11:
72 x 11 = 792 [ outer figures are 72 & add the middle figures ]
98 x 11 = 1078 [ addition of middle figures is two digit number ]
235 x 11 = 2585 [outer figures 25 & sum of 2,3 & 3,5 ] similarly 563 x 11 = 6193
6. How to find cube of a number: (23)3 = 12167 , let a = 2 & b = 3, use formula of cube
