The world of mathematics is filled with intriguing mysteries and challenges that have captivated human imagination for centuries. One such math mystery that we will explore in this article is the calculation of 2x9x9x2. At its core, this expression represents a simple arithmetic operation, but as we delve deeper, we will uncover the underlying principles and rules that govern its solution.
Understanding the Order of Operations
To tackle the math mystery of 2x9x9x2, it’s essential to understand the order of operations, a fundamental concept in mathematics that dictates the sequence in which we perform arithmetic operations. The acronym PEMDAS, which stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right), serves as a helpful reminder of this order. In the case of 2x9x9x2, we have only multiplication operations, so we will perform them from left to right.
Applying the Order of Operations to 2x9x9x2
Now, let’s apply the order of operations to our math mystery. We start with the first operation from the left: 2x9. Multiplying 2 by 9 gives us 18. Then, we move to the next operation, which is 18x9. The result of this multiplication is 162. Finally, we have 162x2. Multiplying 162 by 2 yields 324. Therefore, the solution to the math mystery of 2x9x9x2 is 324.
| Operation | Result |
|---|---|
| 2x9 | 18 |
| 18x9 | 162 |
| 162x2 | 324 |
