The first six digits of the first formula and the second formula are the same, and then the first formula = 18, so the first six digits of the second formula are also 18, leaving two ○, 20- 18 = 2 and two ○= 1.

From the third formula: 2 stars +2 squares = 14, then star+square =7 and star =7 squares.

The first formula is: 3 stars +2 squares+1○= 18. From ○= 1, 3 stars +2 squares = 17.

Release? Star =7 square substitution? 3 stars +2 squares = 17, so:

3(7 square) +2 square = 17

2 1-3 square +2 square = 17

2 1 square = 17

Square =4

Again? Square =4 substitution? Star =7- square？ Medium, star =3

Get: ○= 1, ☆=3, □=4.
