You borrowed 10000 yuan and paid it back to 850 yuan in twelve installments (ten thousand divided by 12 installments equals 833+ 17 yuan interest =850).

Your credit line was originally 10000 yuan, and you borrowed 10000 yuan, so the credit line is empty at this time, and it will be displayed as 0, with repayment in installments and 850 yuan in each installment. Your first repayment will increase your account by 833 yuan. As I said just now, the repayment of 850850 yuan per installment is from 10000 yuan to 12 installment =833, so when you repay 12 installment, 12x 833 = 10000. Then you can pay it back then, and you can borrow it after you pay it back. You can't borrow it without paying it off, so the balance you show now is more and more, not owing, but your limit!
