Sorry,
This isn't a homework question. I'm just having trouble understanding some of the notes I've taken down.I'd really appreciate if some of you could help me understand this.
________________
1/3 is that number with the property
(1/3)(3) = 1
...
what is 7^(-1) mod 10?
7^(-1) ≡ 3 mod 10
because 7 * 3 ≡ 1 {21 - 2(10)= 1}
____________
Is it ≡ to 3 because 7 by 3 gives you 1 like in the case of 1/3.
but I'm not multiplying 7^(-1) by 3?
If someone could help me understand this it would be really appreciated.
