Yes, it is related to p- adic numbers. I found the solution in wikipedia. Thanks Dick=)

I think it cannot be solved by using complex numbers

As you know our decimal expansions have the form \pm d_n d_{n-1} \dots d_2 d_1 d_0.d_{-1}d_{-2}\dots where each d_i is in \{0,1,\dots,9\} We can have infinitely many nonzero digits after the decimal point, but we must have only finitely many nonzero digits before the decimal point. In Tersonia...

I think we should use cyclic numbers

145827 is not part of the problem. for instance, when you show -1 in tersonian decimal expansion: you should write " consider a number y= \overline{9}.0=\dots9999.0 . Then 10y= \dots 9990.0 and -9y=9 . Therefore y=-1 so -1=\overline{9}.0" I mean I need a tersonian decimal expansion which...

yes, I searched it too. My teacher said "Here are some problems from Tersonian Elementary School Mathematics Book:" For instance , y=\overline{12}.0 is a Tersonian decimal expansion. Normally, decimal expansions are in after the comma but in tersonian, expansions in before the comma.

Homework Statement x and y are non-zero numbers. Homework Equations x.y=0 The Attempt at a Solution I think we should use cyclic numbers but How?

Homework Statement 1/7=? Homework Equations The Attempt at a Solution Consider $$y=\overline{145827}.0=\dots145827145827145827.0$$, then $$1000000y=\dots 145827145827000000.0$$ and $$-999999y=145827$$ . Therefore, $$y=-\dfrac{145827}{999999}$$ . Son in fact...
