Try solving it without a calculator—use your mind

Here’s a math challenge: solve 11 – 11 × 11 + 11 = ?

Many get it wrong initially because they forget the order of operations, remembered by BODMAS

(Brackets, Orders, Division/Multiplication, Addition, Subtraction).

There are no brackets or orders here, so first multiply 11 × 11 = 121, turning the equation into 11 – 121 + 11.

Then add 11 to -121, getting -110.

Finally, subtract: 11 – 110 = -99. The correct answer is -99.
