Triangle yellow =1;

Triangle blue = 2;

Round yellow =1;

Triangle orange = 3;

Circular blue = 2;

Then, we can fill in the following table according to the graphic values above:

2= triangle yellow+circle yellow = 1+ 1

4= triangle blue+circle blue =2+2

3= triangle yellow+circle blue = 1+2

5= triangle orange+circle blue =3+2

Because the calculated value is relatively small, you can assume several graphic values first, and finally see how much to make up for what is missing. If the assumed values are different, the values of the answers may be different.
