Gave a task to solve a logical problem. The point is that in under each letter the figure is encrypted. As a result, during small mathematical manipulations we receive these results (300,000, 1879, 1905). The main objective is to decipher figures under letters.

From 1 equation of EIN*ST*EI*N = 300,000 = 3*2^5*5^5 = 125*40*12*5 E = 1; I = 2; N = 5; S = 4; T = 0 Of 2 equations of EI*NS - TE*IN = 1879 = 89*51 - 28*95 E = 8; I = 9; N = 5; S = 1; T = 2 Of 3 equations of EI*NS + TE*IN = 1905 = 52*30 + 15*23 E = 5; I = 2; N = 3; S = 0; T = 1 I solved the First itself, the second and third by means of the program.
