A challenge for maths enthusiasts
This intriguing puzzle was shared on X (formerly known as Twitter) by a page named @Brainy_Bits_Hub. The brain teaser starts with a set of seemingly straightforward equations, but as you explore them further, they introduce a twist that has left many baffled.
The first part of the puzzle reads, "A + A = 2," which simply implies that adding two A’s results in 2. Likewise, the equation "B + B = 4" suggests that two B’s sum up to 4. From these, you can deduce that A equals 1 and B equals 2.
But here’s where things get interesting. The final part of the brain teaser presents the expression: "A + B × 2 = ?" While it seems simple, the order of operations throws many off. Solving this requires a careful understanding of how multiplication and addition should be approached.
