Question

Find a+b:

731≡a mod(6) and 93 ≡ b mod(7)

Answer 1

Would it be...
731 mod(6) = a
(Find a)
And
93 mod(7) = b
(Find b)

Then find a+b ?

Answer 2

Or use,
\[c\equiv a \mod (m)\\
d\equiv b \mod (m)\\
(c+d)\equiv (a+b)\mod (m)\]

Answer 3

But one is mod 6, another one is mod 7?

Answer 4

if:
(c+d) ≡ (a+b) mod m
it implies that (a+b)≡(c+d) mod m

but the first equation is mod 6 and the other one is mod 7...

Answer 5

Can't you just find 731mod(6) and 93 mod(7) and then add them?

Answer 6

True, :), @RolyPoly is right.

Answer 7

I thought that it was wrong so i asked you guys.. thanks :)))
