MAGIC SQUARE: Calculate A*B-C
The aim is to place the some numbers from the list (4, 5, 6, 7, 12, 13, 24, 52, 62, 64, 70) 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.

Sir John LeslieDied 3 Nov 1832 at age 66 (born 10 Apr 1766). Scottish physicist and mathematician who first created artificial ice. His practical scientific investigations led to his book Experimental Inquiry Into the Nature and Propagation of Heat (1804), dealing with the fundamental laws of heat radiation. Leslie gave the first correct description of capillary action (1802) and invented many instruments, most notably an accurate differential air thermometer, and also a hygrometer, a photometer, the pyroscope, atmometer and aethrioscope. In 1810, he devised a method of obtaining very low temperatures, by evaporating water in a receiver evacuated with an air-pump but containing a drying agent. His mathematical works include texts on geometry, trigonometry and The Philosophy of Arithmetic. |
