Quick question on the characteristic of a ring.

Click For Summary
SUMMARY

The discussion centers on the characteristic of a ring, specifically addressing the scenario where na=0 with n≠0 and a≠0. The contributor asserts that if p is the characteristic and p < n, applying the division algorithm to n by p demonstrates that the remainder is 0, confirming that n is a multiple of the characteristic. This approach is validated by the community, indicating that the method used is sound and leads to the correct conclusion regarding the properties of ring characteristics.

I was looking back at a proof I did a while ago. Suppose na=0 with n≠0 and a≠0. Then n is a multiple of the characteristic. I supposed p < n is our characteristic, then I simply used the divison algorithm (I divided n by p) and the distributive property which lead to the remainder being 0. From there, I concluded the desired result. I don't want to bore anyone with the details, but does that seem like a valid approach.

Thanks! :shy:
