Explanation of the Transformation from Minus 49 to Plus 49

When opening a bracket, the transformation of minus 49 to plus 49 may be related to the context in which the transformation is occurring. Without specific context, it's difficult to provide a precise explanation. However, in some programming languages, such as Python, the use of parentheses can affect the sign of a number if it is placed immediately after the opening parenthesis. This can be seen in mathematical expressions or when assigning negative numbers within parentheses.

In the context of programming, the use of parentheses can change the sign of a number due to the way negative numbers are represented and the rules of operator precedence. It's important to consider the specific programming language and the surrounding code to understand the exact reason for this transformation.
