# Mark four numbers forming a square in a calendar:Add the squares of the diagonal pair and find the difference of these sums:42 + 122 = 160112 + 52 = 146160 – 146 = 14Do this for other four numbers.

Let the numbers be 6,7,13 and 14

the squares of the diagonal are

62 and 142

72 and 132

Add the squares of the diagonal pair

62 + 142

= 36+196

= 232

72 + 132

= 49+ 169

= 218

find the difference of these sums:

232 - 218

=14
