Perform the following congruence computations. Make sure that the number you enter is $\geq 0$ and $\leq N-1$, where $N$ is the modulus of the congruence.

$2839 + 6150 \equiv$ $\pmod{51}$
$8082 - 95*5806 \equiv$ $\pmod{53}$
$74705 +$ $-477 \equiv 627*462 \pmod{84}$
$803 * (61677 - 286) * 5809 - 304 \equiv$ $\pmod{71}$
$8556^{4} \equiv$ $\pmod{92}$
