It is possible to get 1500 using the digits 1 through 9 by combining them in mathematical operations. For example, you can use addition, multiplication, or concatenation of numbers. One way to achieve this is by calculating ( 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 = 45 ) and then multiplying by 33, as ( 45 \times 33 = 1485 ), and adjusting through additional operations. However, a direct combination of operations or concatenating digits strategically can also be devised to reach exactly 1500.
