Think of atleast two situations in each of which you need to form two algebraic expressions and add or subtract them:

Can you think of two more such situations., where we may need to multiply algebraic compressions ?

Give two examples of situations in which applied force causes a change in the shape of an object.

Give two examples each of situations in which you push or pull to change the state of motion of objects.

Observe the patterns of shapes of letters formed from line segment of equal lengths. If n shapes of letters are formed, then write the algebraic expression for the number of line segment required for making these n shapes in each case.
