If the external graphic value is small, add it. Result = external graph value+internal graph value
Specific analysis:
The first two graphs are square and round, with large added value and small impairment. Can you understand this?
So you can know that the first figure is additive, that is, the square is smaller than the circle, then
Square and circle of the first figure =3.
The square of the second graph circle reduction = 1
So the square is equal to 1 and the circle is equal to 2.
Next, by analyzing Figure 3 and Figure 4 in the same way, we can know that
Third number plus triangle =6.
The fourth graphic triangle is reduced by 4 times.
So the triangle is equal to 5.
The last picture is a triangle with a reduced circle =5-2=3.
