SUMMARY
Euler defines a variable as "an indeterminate or universal quantity, which includes within itself all completely determined values." This indicates that a variable can represent any numerical value, encompassing both constants and complex values. The term "completely determined values" refers to constants established earlier in the text. Furthermore, Euler emphasizes that a variable remains undetermined until a specific value is assigned through computation.
