Here are three addition formulas. What numbers do square, triangle and circle represent to make the equation hold? □ + □ + △ + Θ = 20 （1） □+△+△+○=17…… （2） □+△+○+○=15…… （3）

Here are three addition formulas. What numbers do square, triangle and circle represent to make the equation hold? □ + □ + △ + Θ = 20 （1） □+△+△+○=17…… （2） □+△+○+○=15…… （3）

1. Sum of three figures: (20 + 17 + 15) △ 4 = 13
2. Square: 20-13 = 7
3. Triangle: 17-13 = 4
4. Round: 15-13 = 2

Triangle, circle and square represent three numbers
And triangle + triangle = square + square + square, square + square + square=
Circle + circle + circle + circle, triangle + square + circle + circle = 400
Triangle = (); square = (); circle = ()

Triangle + triangle = square + square + square, square + square + square=
Circle + circle + circle + circle, triangle + square + circle + circle = 400
Triangle = (150); square = (100); circle = (75)
Do with multiple relation

The formula of a vertical calculation is △ □ × [= 2 □ □ △. Note that the number of two triangles is the same, the number of four squares is the same, and finally it is equal to this number

499*6=2994
599*5=2995
There are only two

The same symbols in the formula of □ △ ＋ □ △ ＋ □ △ = 888 represent the same numbers. What numbers do square, five pointed star and triangle represent

Because the three numbers are the same, 888 △ 3 = 296
The square represents two, the five pointed star represents nine, and the triangle represents six
