4 Digit number Minus 3 Digit number = 3 Digit number - Hard part is all digits must be different between 0 & 9

Hard part is all digits must be different AND between 0 --> 9.

2456 - 781 = 1675 :mrgreen:

2456 - 781 = 1675

No. Must equal a 3digit number.

There's 96 solutions: from 1026 - 437 = 589 to 1602 - 859 = 743

No. Must equal a 3digit number.

Also, we can't have the repeats of digits 1, 5, 6, and 7.

But Aladdin got the part about digits between 0 and 9 correct!
