The image is a photograph of a whiteboard in a classroom. The whiteboard is rectangular in shape and has a yellow background. On the left side of the whiteboard, there is a list of mathematical equations written in black marker. The equations are written in a neat and organized manner, with each equation having its own set of numbers and symbols. 

On the right side, there are two columns of numbers, one labeled "1" and the other labeled "2". The first column is labeled "3", the second column is numbered "4", and the third column is filled in with the same numbers. The numbers are arranged in a grid-like pattern, with the first column being the largest and the last column being smaller.

At the bottom of the image, there appears to be a desk or a bulletin board with a few markers on it.
