Summarize this article for a 10 year old
Standard Adding Machine Company was founded in the early 1890s (first records are from 1892)[2][3][4] in Illinois and was the first company to (successfully)[5] release a 10-key adding machine. The machine was a breakthrough for its time because it dramatically modernized computing. Earlier key driven adding machines, like the comptometer, featured eight or more columns of nine keys, which made them cumbersome and costly and their operators prone to mistakes. The 10 keys were set on a single row.
