Solving the Viral Einstein Math Puzzle: 5 + 11 = ?
Math riddles and pattern-recognition puzzles regularly go viral across social media feeds. Featuring striking visuals—like an outdoor mural of Albert Einstein paired with a sequence of unconventional equations—these brain teasers invite scrollers to uncover the underlying rule and solve the final line.
At first glance, the equations seem mathematically incorrect because standard addition isn’t being used. Instead, the plus symbol ($+$) acts as an operator for a hidden mathematical pattern.
In this guide, we break down the step-by-step logic, explain the primary formula that solves the riddle, evaluate secondary interpretations, and explore why math puzzles generate massive online participation.
Step-by-Step Solution: Finding the Pattern
To solve the puzzle, we need to determine the rule that transforms the input numbers $(a, b)$ into the output value $(c)$ across every given line.

[ THE FORMULA: a + (a × b) ] [ ALTERNATIVE FORM: a × (b + 1) ]
• Row 1: 1 + (1 × 5) = 6 • Row 1: 1 × (5 + 1) = 6
• Row 2: 2 + (2 × 6) = 14 • Row 2: 2 × (6 + 1) = 14
• Row 3: 3 + (3 × 7) = 24 • Row 3: 3 × (7 + 1) = 24
• Row 4: 5 + (5 × 11) = 60 • Row 4: 5 × (11 + 1) = 60
Method 1: The Multiplication-Addition Pattern ($a + a \cdot b$)
In this pattern, you multiply the two numbers together and then add the first number to the product:
- Line 1: $1 + (1 \times 5) = 1 + 5 = 6$
- Line 2: $2 + (2 \times 6) = 2 + 12 = 14$
- Line 3: $3 + (3 \times 7) = 3 + 21 = 24$
- Line 4: $5 + (5 \times 11) = 5 + 55 = \mathbf{60}$
