So x + x is equal to 2x because you’re adding two equal things (two x ). Similarly, x + x + x equals 3x because you’re adding three of the same thing (three x ’s). In the realm of mathematics, equations like x×x×x = 2x \times x \times x = 2x×x×x =2 (or x3=2x^3 = 2x3 =2) represent more than just numbers and symbols—they reveal relationships, challenge logic, and lead to essential principles in algebra, calculus, and real-world applications. The expression " x " x " x " is equal to x ^3, which represents " x " raised to the power of 3. In mathematical notation, x ^3 means multiplying x by itself three times: Automatically Solve Problems.
