The image shows a whiteboard with some mathematical expressions written on it. The background appears to be an indoor setting, possibly a classroom or office, given the presence of a whiteboard and writing materials.

Here's a detailed description of what is visible:

1. Mathematical Expressions:

   • There are several mathematical formulas and equations written in black marker.
   • Some of these include variables like ( x ), ( y ), and numbers such as 2, 3, and 5.
   • The expressions involve addition, subtraction, multiplication, and division operations.

2. Whiteboard:

   • The whiteboard is plain white and has no additional decorations or designs.
   • It serves as a medium for displaying educational content or solving problems.

3. Environment:

   • The surroundings suggest an academic or professional environment due to the use of a whiteboard.
   • There might be other items around, but they are not clearly visible in this image.

This setup is typical for teaching or problem-solving sessions where complex mathematical concepts are discussed or worked out step-by-step.
