Brain Test Level 137 Walkthrough & Answer

## Question **Brain Test Level 137:** Type the answer: What is 0.1 + 0.2? ## Answer The answer is 0.3 — NOT 0.30000000000000004. Brain Test wants the human answer, not the computer one. ## Step-by-Step Walkthrough If you know programming, you might hesitate because 0.1+0.2 famously equals 0.30000000000000004 in floating-point arithmetic. But Brain Test wants the simple human answer: 0.3. Here is exactly how to solve Brain Test Level 137: 1. Read the question carefully — Brain Test loves wordplay and misdirection. 2. Look at every element on screen, including the question text itself. 3. Just type 0.3 — this is a math question, not a programming challenge. 4. If you are stuck, remember that Brain Test rewards lateral thinking over logical answers. ## Why It's Tricky Knowledge interference from programming creates doubt in tech-savvy players. The floating-point meme is so well-known that developers overthink this simple arithmetic problem. Sometimes your first instinct IS correct — Brain Test plays both ways. ## Why This Level Is Tricky For difficulty 4, expand your toolkit: try shaking the device, using the volume rocker, covering the camera, or pressing the home button area. Also try dragging seemingly static elements like the level number, score display, or hint button. Brain Test treats everything on screen as a potential puzzle piece at this tier. Mid-game levels (51-150) start combining multiple trick types in one puzzle. You might need both wordplay and physical interaction to solve a single level. If one approach fails, switch to a completely different trick category. ## Common Mistakes Players frequently make these errors on Level 137: - Fixating on the visual scene and ignoring the question text, which often contains the key wordplay or clue. - Trying the same approach repeatedly instead of testing a completely different interaction method. - Forgetting that some levels require physical phone actions — shake, tilt, rotate, or cover the camera.
