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 =
