Puzzle #1

Students: Print this page - then write your name at the top. The 
numbers in the bottom row and in the right most column are the totals 
for the columns, rows and the left-to-right, top-to-bottom diagonal - 
they are shown in bold type. The block of numbers has some numbers 
missing - see the empty boxes. Fill in those numbers so that the 
totals for all rows, columns and the left-to-right, top-to-bottom 
diagonal match the totals shown.
