What integer $n$ satisfies $0\le n<18$ and $$n\equiv -11213141\pmod{18}~?$$
\(\text{Find }0 \leq n < 18 \ni n \equiv -11213141 \pmod{18}\)
\(\dfrac{11213141}{18} = 622952 + \dfrac{5}{18} \text{ so }\\ -11213141 + 622953\cdot 18 = 13 \equiv -11213141 \pmod{18}\)
Hi Rom,
What is the back to front e thingy ?
Melody, for "the back to front e thingy" read "such that".
Thanks Alan :)
