You asked:

Evaluate the congruence relation statement $78 \equiv 0 \pmod{7}$.

MathBot Answer:

This congruence relation statement is not true.

Two expressions $a$ and $b$ are congruent modulo $n$ if $a - b$ is a multiple of $n$.

$78 - 0 = 78$, which is not a multiple of $7$, so the congruence relation statement is not true.

This is because dividing $78$ by $7$ produces $11$ with a non-zero remainder of $1$.
