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

## Question _ + _ = _

_ + _ = _

_ + _ = _

_ + _ = _

Fill the blanks with numbers above, so:

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

I believe I did the equations correctly...

Spoiler

First equation: Numbers: 851, 1998, 9512

Forwards: 851 + 8661 = 9512        Backwards: 158 + 1998 + 2156

Second equation: Numbers: 1091, 1501, 2652

Forwards: 1091 + 1501 = 2592      Backwards: 1601 + 1051 = 2652

Third equation: Numbers: 1101, 1181, 2822

Forwards: 1101 + 1181 = 2282      Backwards: 1011 + 1811 = 2822

Fourth equation: Numbers: 1801, 1901, 2982

Forwards: 1081 + 1901 = 2982      Backwards: 1801 + 1061 = 2862
