Free Trade Math Simulators: 48 Real-World Scenarios for Electricians, Plumbers, HVAC Techs, Carpenters, and Welders

America has 3 million unfilled trade jobs. Meanwhile, up to 60% of trade school students never complete their programs.

The #1 reason? Math.

Not calculus. Not trigonometry. Basic trade math: fractions on a tape measure, voltage drop calculations, pipe sizing, BTU loads, board feet.

Today, Global Sovereign University is launching something that doesn't exist anywhere else: six free interactive trade simulators with 48 real-world job scenarios.

What We Built

Each simulator puts you in the boots of a working tradesperson facing actual job-site calculations:

⚡ Electrician Simulator — Ohm's Law, voltage drop, load calculations, NEC code compliance. Wire a house. Pass inspection. Build your reputation.

🔧 Plumber Simulator — Pipe sizing, drainage slope, fixture units, pressure calculations. Size the system right or face callbacks.

❄️ HVAC Simulator — BTU calculations, CFM requirements, duct sizing, refrigeration diagnostics. Keep them comfortable or lose the customer.

🔨 Carpenter's Challenge — Board feet, rafter cuts, stair calculations, material estimates. Measure twice, cut once — or waste materials.

🔥 Welder Simulator — Heat input, fillet sizing, electrode selection, AWS code requirements. Lay clean beads or fail inspection.

🏭 TPM Challenge — Manufacturing operations, Total Productive Maintenance, OEE optimization. Run a plant without running it into the ground.

Why This Matters

Every scenario presents the same information a real job ticket would: specifications, code requirements, and a formula hint. You choose your answer. The simulator shows you exactly why you're right — or exactly where your calculation went wrong.

This isn't abstract math class. This is the math that determines whether a house catches fire, a pipe bursts, or a weld fails under load.

No Catch

These simulators are free. No account required. No ads. No subscription.

Global Sovereign University is a 501(c)(3) educational foundation. Our mission is simple: Building a Bridge to Freedom Through Education — Not Handouts.

We don't believe in giving people fish. We believe in teaching people to fish. And for millions of Americans, the skilled trades are the fastest path to a good living without crushing debt.
