If ba8c0 - a0bb8 = aac3b find number abc. Multiple solutions may exist.
NUMBERMANIA: Calculate the number 5084 using numbers [3, 8, 3, 9, 38, 644] and basic arithmetic operations (+, -, *, /). Each of the numbers can be used only once.
The aim is to place the some numbers from the list (15, 16, 17, 18, 23, 24, 42, 44, 50, 58, 98) into the empty squares and squares marked with A, B an C. Sum of each row and column should be equal. All the numbers of the magic square must be different. Find values for A, B, and C. Solution is A*B+C.

Oswald Veblen

Born 24 Jun 1880; died 10 Aug 1960 at age 80.American mathematician who made important contributions in early topology, and in projective and differential geometry - work which found applications in atomic physics and the theory of relativity. In 1905, he proved the Jordan curve theorem, which states that every non-self-intersecting loop in the plane divides the plane into an "inside" and an "outside". Although it may seem obvious in its statement, it is a very difficult theorem to prove. During WW II, he was involved in overseeing the work that produced the pioneering ENIAC electronic digital computer. His name is commemorated by the American Mathematical Society's Oswald Veblen Prize. Awarded every five years, it is the most prestigious award in recognition of outstanding research in geometry.«

The Blessing – You may have lived this one

Joan invited some people to dinner. At the table, she turned to her six-year-old daughter and said, 'Would you like to say the blessing?'
'I wouldn't know what to say,' the girl replied.
'Just say what you hear Mommy say,' Joan answered.
The girl thought for a minute, then bowed her head and said, 'Lord, why on earth did I invite all these people to dinner?'
