# Arrange numbers to the equations, so if we turn the equations upside down, they are still right

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

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.
• how to interpret 150 when reversed? 51? – stack reader Dec 5 '16 at 8:45
• It must be 1501, I will replace the picture. – Jamal Senjaya Dec 5 '16 at 8:52

I believe the equations are:

 851 + 8661 = 9512 158 + 1998 = 21561091 + 1501 = 25921601 + 1051 = 26521801 + 1061 = 28621081 + 1901 = 29821101 + 1181 = 22821011 + 1811 = 2822

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
