851, 1091, 1101, 1181, 1501, 1801, 1901, 1998, 2652, 2822, 2982, 9512

_ + _ = _
_ + _ = _
_ + _ = _
_ + _ = _

Fill the blanks with numbers above, so:

  • The 4 additions are right.
  • All numbers must be used.
  • If we turn the additions upside down, they are still right, so there are 8 additions.
  • You can rotate any numbers too, example 1091 -> 1601.

I believe the equations are:

 851 + 8661 = 9512
158 + 1998 = 2156

1091 + 1501 = 2592
1601 + 1051 = 2652

1801 + 1061 = 2862
1081 + 1901 = 2982

1101 + 1181 = 2282
1011 + 1811 = 2822

Here is the answer

2822 -> 2282
1181 + 1101 = 2282
2822 = 1011 + 1811

1901 -> 1061
2982 -> 2862
1801 + 1061 = 2862
2982 = 1901 + 1081

2652 -> 2592
1501 + 1091 = 2592
2652 = 1051 + 1601

1998->8661
8661 + 815 = 9512
2156 = 518 + 1998
