Finding Distance Between Points: From 0 to F on Number Line

Q: How can the distance be zero if we're measuring from 0 to F?

Great question! The key is that F is located AT position 0 on the number line. When you're measuring distance from a point to itself, the distance is always zero.

Q: What does distance mean on a number line?

Distance means how many units apart two points are. It's always a positive number (or zero if they're the same point). Think of it as counting steps between positions.

Q: Why isn't the answer 1 since there's one letter between 0 and F?

Don't count letters - count positions! F and 0 are both labels for the same spot on the number line. The distance is measured by the numerical difference, not the number of different labels.

Q: How do I read the number line correctly?

Look at the numbers below each point, not just the letters above. The letters are just names - the numbers tell you the actual positions. F sits right above the number 0.

Q: Is distance ever negative?

No! Distance is always positive or zero. Even if you go from 3 to -2, the distance is still 5 (not -5). Distance measures how far apart things are, regardless of direction.

Understand the problem

What is the distance between 0 and F?

Step-by-step solution

Let's begin by marking F and 0 on the number line

We can thus determine that:

$F=0$

Therefore, the distance is 0 steps.

Final Answer

Key Points to Remember

Essential concepts to master this topic

Same Position: When two points occupy identical locations, distance equals zero
Technique: Identify position: F is at 0, so distance from 0 to F = 0
Check: Count steps between points: 0 steps from F to itself ✓

Common Mistakes

Avoid these frequent errors

Assuming different letters mean different positions
Don't assume F and 0 are at different locations just because they use different labels = counting phantom steps! Letters are just names for positions. Always read the number line carefully to see where each point is actually located.
