9 21 24 15 30 36 39 45 51 how to make every row, every column, every diagonal row add up to 90

36 9 45 39 30 2115 51 24 the idea is as follows: 1 - from big to small, the fifth is 30 in the middle, it must be in the middle lattice. 2 - other numbers become pairwise collocation to form 60, which is simple. For example, the largest 51, only the smallest 9 can match it to form 603 - through the above two steps, through the four groups in the center, it will come out

Among the numbers 57, 1, 29, 2, 39, 49, 52, 9, 21, 43, 51 and 77, which are prime numbers and which are composite numbers?

Among the numbers 57, 1, 29, 2, 39, 49, 52, 9, 21, 43, 51 and 77, 29, 2 and 43 are prime numbers, and 57, 39, 49, 52, 9, 21, 51 and 77 are composite numbers
