Use the method of exclusion+enumeration

The first thing to make sure is spring:

Spring cannot be 0, 1, otherwise the equation cannot.

Can't carry it, so red × spring.

If the springs are 5, 6, 7, 8 and 9, then the red color can only be 1, and the blade × spring position of 1 can only be 99=8 1, which is obviously wrong, so the spring can only be one of 2, 3 and 4.

If spring is 2, because red x spring.

If spring is 3, because red x spring.

Discharge spring =0, 1, 2, 3, 5, 6, 7, 8, 9, so it can be concluded that the spring is 4.

The second one is red:

Red× Spring (4)

In this way, you can determine:

2

× 4

= 2

Namely:

2 flowers reflecting green leaves

× 4

= green leaves and flowers 2

The third is to determine the leaves.

Leaves× 4 = Numbers with mantissa of 2, only 3 and 8, and the result of 2×4=8 is at least 8 digits, so leaves can only be 8.

Fourth, determine the flowers.

2 flowers 8

× 4

= 8 flowers 2

Hua× 4 = The result has no carry, and 2 has been used, so it can only be 0, 1: If it is 0, then Green× Spring (4)+3 (3 digits) = The mantissa of the result is 0, which is obviously invalid, so the flower can only be 1.

Namely:

2 1 8

× 4

= 8 1 2

Fifth, determine green.

2 1 ? Grade 8

× 4

= 8 green? 1 2

4× green +3= The mantissa of the result is 1. List the results. Because the maximum green is 9, the result can only be 1 1, 2 1, 3 1. If you substitute, you can know that green is 7.

2 1 ? 7 8

× 4

= 8 7 ? 1 2

Finally, it is simple to determine the projection, and it is determined to be 9.

The answer is:

Red flowers reflect green leaves =2 1978

Spring =4

Leaf green reflection bonus =879 12
