## anonymous 5 years ago anyone know how to explain Modular additon and congruent modulo m?

1. anonymous

a and b are congruent modulo m $$\iff \exists k \text{, such that } km = a-b$$

2. anonymous

oh, $$k \in \mathbb{Z}$$

3. anonymous

ok im sorry but, i didnt understand any of that. ive never seen those symbols, still having trouble comprehending

4. anonymous

I just means that $$\frac{(a-b)}{m}$$ will be an integer.

5. anonymous

I know the E written on the bottom stands for element

6. anonymous

$$\exists$$ means "There exists". $$\iff$$ means "if and only if".
