Fill the eight numbers 2, 3, 4, 5, 6, 7, 8 and 9 in the following eight boxes (which can't be repeated) to form many different subtraction formulas. If you want to minimize the calculation result and make it a natural number, the calculation result will be zero______ ．□□□□-□□□□
6234-5987 = 247
Use the nine numbers 1-9 (each number can only be used once) to form a three digit minus three digit formula. Is the difference also a three digit formula?
Are you two copying each other?
783 - 124 = 659864 - 125 = 739486 - 127 = 359495 - 127 = 368495 - 128 = 367567 - 128 = 439486 - 129 = 357567 - 129 = 438783 - 129 = 654864 - 129 = 735792 -
