Math's polite word for 'do this part first, I dare you.'
means A collection of things gathered together and treated as a single unit, often because of shared properties or position.
from From 'group,' borrowed into English from French 'groupe' in the 1600s-1700s, itself from Italian 'gruppo' — originally an artistic term for a cluster of figures arranged together in a painting or sculpture. The '-ing' turns the act of clustering into the thing clustered. So the word carries a faint echo of studio composition: even in algebra, you're still arranging figures into a pleasing, manageable cluster.
