I'm reading a textbook of mathematics 'What is mathematics?' and I've got a problem with septimal system.
Symbol 10416 in the septimal system denote 2610 (decimal system).
[itex] 1*7^4+0*7^3+4*7^2+1*7+6 = 2610 [/itex]
But I can't understand why 7416 in the septimal system denote 2610 too.
[itex] 7*7^3+4*7^2+1*7+6 = 2610 [/itex]
Where is my mistake?
