Left image: The image shows a boy annoyed with studying maths. Behind him is a board with lots of shapes like  semi-circle and trapezoid drawn along with mathematical formulas like areas of circle. There is a graph of sinusodial curve also drawn on the board.
Right image: The image shows a boy wearing a cap with a skateboard in his hands. He is happy. In his background there is a skateboard park. In the background there is a person skateboarding on a semi cirular bowl. We also see bowls of other shapes like trapezoid and sine wave.
The image is ironical beaucse while the boy does not enjoy studying mathematics and different geometric shapes like semi circle and trapezoid and graphs of trigonometric equations like that of a sine wave, he enjoys skateboarding on surfaces and bowls that are built based on the said geometric shapes and graphs of trigonometric equations.
