Factory calculators are used by financial advisors and business officers to help customers and clients with tasks like purchasing a car. The calculator takes in information like the listed car price, down payment, interest rate, and loan term to calculate the monthly payments and show if the budget can afford it. This helps evaluate options and make the payments more reasonable. Factory calculators are faster, cheaper tools that are becoming more affordable and available to companies. They can solve various mathematical problems to help with tasks like production scheduling and flexibility.
