show me your calcualte process

As an AI language model, I don't have a physical calculator to show you my calculation process. However, I can explain how I process calculations.

When you input a mathematical expression, I analyze it and break it down into smaller components such as numbers, operators, and variables. Then, I use algorithms to perform the arithmetic operations in the correct order of operations (parentheses, exponents, multiplication and division, addition and subtraction) to arrive at the final result.

For example, if you input "5 + 4 * 3 / 2 - 1", I would first perform the multiplication and division operations, then the addition and subtraction operations, following the order of operations. The calculation would be:

(4 * 3) / 2 = 6

5 + 6 - 1 = 10

Therefore, the final result would be 10.
