Given

Starting at 0 on a number line, a point is moved 21 units, then 53 units, then 721 units, and finally negative-50 units.

To find:

Where has the point moved to?

Step-by-step explanation:

It is given that,

Starting at 0 on a number line, a point is moved 21 units, then 53 units, then 721 units, and finally negative-50 units.

That implies,

Since starting at 0 on a number line, a point is moved 21 units.

Then,


0+21=21

Also, then 53 units.

Then,


21+53=74

Also, then 721 units.

Then,


74+721=795

And, finally negative-50 units.

Then,


\begin{gathered} 795+(-50)=795-50 \\ =745 \end{gathered}

Hence, the point is moved to 745.
