In Walter Isaacson's book about Leonardo da Vinci, it is revealed that while da Vinci excelled in geometry, he struggled with algebra and equations. This highlighted a contrast in his mathematical abilities, showcasing his strength in spatial reasoning over more abstract mathematical concepts.
This distinction is significant as it underscores da Vinci's unique approach to science and art. He relied on geometric principles in his works, allowing him to innovate and create, even though he did not conform to the mathematical standards of his era.
