e^{i\pi} + 1 = 0

\int_0^1 x^2 \, dx = \tfrac{1}{3}

\frac{d}{dx} \sin x = \cos x

\sum_{n=1}^{\infty} \frac{1}{n^2} = \frac{\pi^2}{6}

a^2 + b^2 = c^2

\lim_{x \to 0} \frac{\sin x}{x} = 1

P(A \mid B) = \frac{P(A \cap B)}{P(B)}

\binom{n}{k} = \frac{n!}{k!\,(n-k)!}

Nalariva Arena

A class arena that feels lively, orderly, and honest

Arena is built for busy class sessions that still feel organized: students move through a clear question rhythm, the host stays in control, and the leaderboard only exists inside the active session.

Langkah 1
Masuk pakai kode
Guru membagikan satu kode kelas. Siswa memasukkannya, pilih nama panggilan, langsung siap.
Langkah 2
Menjawab serentak
Semua siswa dapat soal yang sama dengan waktu yang sama, jadi tidak ada yang bisa curi start.
Langkah 3
Papan skor sesi
Skor bergerak langsung selama sesi berjalan, lalu berhenti begitu gurunya menutup sesi.

Arena SessionSiap

One math quiz session for the whole class: the teacher opens the session, students join with a code, then everyone answers the same questions on the same clock. Here is what the screen looks like while a session runs.

Waktu per soal sama untuk semua peserta, jadi tidak ada yang curi start.

Peserta masuk dengan game code, sedangkan hanya tutor yang bisa membuat, memulai, atau menutup sesi.

Koneksi putus di tengah sesi? Masuk lagi dan lanjut dari soal terakhir tanpa kehilangan skor.

Join

Enter the tutor's game code, choose an avatar and nickname, and start without an account login.

Host

Hosts can prepare a session step by step: upload a PDF, review the extracted draft, approve the questions that are ready, then run the live session with clear controls.
