How do you express seventeen correctly in Korean?

To express the number seventeen in Korean, the correct format is a combination of "yeol" which means ten, and the word for seven, "ilgob." Thus, seventeen is expressed as "yeol - ilgob."

In this expression, "yeol" signifies the base ten, and "ilgob" denotes the number seven, effectively combining them to convey the value of seventeen. This structure in Korean numeral systems utilizes the combination of these two components, which is a standard practice for forming numbers above ten.
