Answer:

Rules & Examples of Integers multiplication.

Step-by-step explanation:

A rational number  is a number that can be expressed as a fraction of integers (positive or negative numbers). Every integer is a rational number.

They are multiplied based on following rules :

  • Positive (+) x Positive (+) = Positive (+) , +2 x +2 = 4
  • Positive (+) x Negative (-) = Negative (-) , +2 x -2 = -4
  • Negative (-) x Positive (+) = Negative (-) , -2 x +2 = -4
  • Negative (-) x Negative (-) = Positive (+) , -2 x -2 = 4

The comlete question with the diagram is in the picture attached.

Answer:

Point   \boxed{\text{   E    }}   is the vertex of the angle marked in the figure.

Explanation:

When two lines intersect each other they will form an <em>angle</em> and the intersection point will be the <em>vertex of the angle</em>.

In the figure attached, the line that joins the points A and B and the line that joins the points C and D intersect at the point E, forming the corresponding angle (shadowed in the figure).

Such intersection point, which marks the angle, is the vertex of the angle.
