4. It is used to reserve the logica; state of its operand.

5. '/' Operator divides left side operands with right side operand. Result is the quotient.

    '//' operator is the quotient in which the digits after the decimal points are not taken into account.

Answer in One word.

1. An operator is a symbol which helps the user to command the computer to do a certain mathematical or logical manipulation.

2. Operand are the values or variables, which the operator is applied to. The value of the operands can be manipulated by using operators.

3. Assiggnment Operators : Python assignment operators are used for assigning the value of the right operand to the left operand.

    Relational Operators :- These operators compare the values on either side of the operand and determine the relation between them.

4. Logical operators in python are used for conditional statements are true or false. Logical operators in Python are AND, OR and NOT.

6 Animation is a method in which figures are manipulated to appear as moving images

7 Ctrl + Enter

Answer the following

1. Symbol: A symbol is a reusable object used/created in Flash.

     Instances: An instance is a copy of the original symbol which we drag from the library to the stage.

2. The Timeline determines the timing of the movie, controlling how fast or slow frames are displayed over time. It is also where you create layers, which help you organize the various elements on the Stage. Note the Playhead. The red rectangle will move across the Timeline to show you the current frame on the Stage

3. Frame by frame animation: This type of animation is the traditional style of animation, where we need to draw every frame of animation.

Tweened Animation: In tweened animation, you only create the starting and the ending frames and let flash create rest of the in-between frames.

4. Motion Tweening: In motion tweening , you define properties such as position, size, and rotation of a shape at one point in time.

Shape tweening: In shape tweening , you can create an effect similar to morphing, making one shape Appear to change into another shape over time.
