Question

solve this question without repeating number 1to9 [ ] [ ] [ ]+[ ] [ ] [ ]= [ ] [ ] [ ]​

Answer 1

Use hexadecimal. Then 2+4+5+6+7+8=2016(=3210).

This can actually work with any base from 11 to 19:

1+2+3+4+5+7=2011(=2210)

1+2+3+4+5+9=2012(=2410)

1+2+3+4+7+9=2013(=2610)

1+2+3+6+7+9=2014(=2810)

1+2+3+7+8+9=2015(=3010)

1+4+5+7+8+9=2017(=3410)

1+5+6+7+8+9=2018(=3610)

3+5+6+7+8+9=2019(=3810)

Answer 2

123+321=444
