What does the equivalence sign with the small 3 next to it mean… I’m unfamiliar with that sign.
≡3
Thanks!

This means “is congruent to modulo 3.” For example, 7 ≡3 1 because 7 mod 3 = 1 = 1 mod 3. More formally, a ≡n b iff there exists integral c0, c1, along with an integral k with 0 ≤ k < n, such that a = nc0 + k and b = nc1 + k.
