What was the first computer who successfully performed a long series of arithmetic and logical unit?

The first computer to successfully perform a long series of arithmetic and logical operations was the Electronic Numerical Integrator and Computer (ENIAC). Completed in 1945, it was designed for complex calculations, such as artillery trajectory tables for the U.S. Army. ENIAC was groundbreaking as it was one of the earliest general-purpose electronic digital computers, capable of executing a sequence of operations automatically.
