Represent geometrically on the number line.

Let’s draw a line AB = 3.2 units


Extend this line from B to C by 1 unit.


Now find the mid-point M of AC.


Take M as the center and MA as radius draw a semicircle.


Draw BD ⟘ AC intersecting the semi circle at D.


Then BD =


With B as center and BD as radius, draw an arc, meeting AC produced at E.


Then BE = BD =
