NUMERIA ARENA // RAID MODE

NUMERIA RAID

One boss. The whole class. Solve problems together to bring it down.

WHO ARE YOU?

🎟 I have a login card

Your XP and Gold go to your teacher's leaderboard. No card? Fill in the boxes below.

Your Name

Use your avatar or first name only. Please don't type your last name.

Your Math Teacher

Type the code from your login card in the 🎟 box above. PINs aren't used anymore. No card yet? Ask your teacher.

Choose Your Class

ITEM SHOP

Spend your leaderboard Gold on permanent gear and battle potions.

GEAR CONDITION

Gear wears down 5% every raid it's equipped in. At 0% it stops giving its bonus until repaired.

RAW MATERIALS

Buy materials with Gold — you'll need them to Forge gear or Cook potions below.

FORGE

Forging is a mixture — solve the ratio or proportion correctly to craft the gear. A wrong answer wastes some materials, so you can always try again.

COOK

Cooking scales a recipe up or down — work out the fraction or percent correctly to brew the potion.

JOIN THE RAID

Type the 4-digit raid code from your teacher's screen.

CONNECTION CHECK

You're in raid — waiting for your teacher to start…

Get your brain warmed up. The boss is waiting.

Distance: d = √((x₂−x₁)² + (y₂−y₁)²)
Pythagorean: a² + b² = c²
SOHCAHTOA: sin = opp/hyp · cos = adj/hyp · tan = opp/adj
Area: rectangle = l·w · triangle = ½·b·h · circle = πr²
Volume: prism = l·w·h · cylinder = πr²h
Surface Area: prism = 2(lw + lh + wh) · cylinder = 2πr² + 2πrh
π ≈ 3.14
