Question 3
Mr. Sun has a broken calculator. When just turned on, it displays 0. If the + key is pressed, it adds 35. If the − key is pressed, it subtracts 35. If the × key is pressed, it adds 91. If the ÷ key is pressed, it subtracts 91. The other keys do not function. Mr. Sun turns the calculator on. What is the number closest to 2005 that he can get using this calculator?
