The aim is to place the some numbers from the list (1, 2, 4, 5, 9, 12, 16, 17, 24, 41, 88) 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.
If 9c2b3 - a0a0c = 33ac9 find number abc. Multiple solutions may exist.
What is the missing number in the pattern above?

Louis Essen

Died 24 Aug 1997 at age 88 (born 6 Sep 1908).English physicist who invented the quartz crystal ring clock and the first practical atomic clock. These devices were capable of measuring time more accurately than any previous clocks. He built a cesium-beam atomic clock, a device that ultimately changed the way time is measured. Each chemical element and compound absorbs and emits electromagnetic radiation at its own characteristic frequencies. These resonances are inherently stable over time and space. The cesium atom's natural frequency was formally recognized as the new international unit of time in 1967: the second was defined as exactly 9,192,631,770 oscillations or cycles of the cesium atom's resonant frequency, replacing the old second defined in terms of the Earth's motion.
