Number Line Inequality: Analyzing Why C > E at Positions -3 and -1

Q: Why is -3 smaller than -1 if 3 is bigger than 1?

Great question! With negative numbers, the rules flip. Think of it like debt: owing $3 is worse than owing $1, so -3

Q: How do I remember which negative number is bigger?

Use the number line trick: whichever number is further to the right is always bigger. Since -1 is to the right of -3, we know -1 > -3.

Q: What if I have to compare many negative numbers?

Line them up on a number line or think about their distance from zero. The negative number closest to zero is always the largest negative number.

Q: Does this work for decimals and fractions too?

Absolutely! Whether it's $ -2.5 $ vs $ -1.3 $ or $ -\frac{3}{2} $ vs $ -\frac{1}{2} $, the same rule applies: further right means bigger.

Q: How can I check my comparison is correct?

Try the addition test: if a > b, then a + (positive number) > b + (same positive number). For example, -1 + 5 = 4 and -3 + 5 = 2, and since 4 > 2, we confirm -1 > -3!

Understand the problem

$C > E$

Step-by-step solution

Let's begin by locating the numerical representation of the letter on the number line:

$C=-3$

$E=-1$

Now let's insert the given values in order to test the expression:

$-3>-1$

It appears that the answer is not correct.

Final Answer

Not true

Key Points to Remember

Essential concepts to master this topic

Rule: On number lines, numbers increase as you move right
Technique: Compare positions: -3 is left of -1, so -3 < -1
Check: Verify -3 > -1 is false since -3 is smaller ✓

Common Mistakes

Avoid these frequent errors

Thinking larger negative numbers are greater
Don't assume -3 > -1 because 3 > 1 = wrong comparison! Negative numbers work opposite to positive numbers. Always remember that -3 is further left on the number line, making it smaller than -1.

Why is -3 smaller than -1 if 3 is bigger than 1?

Great question! With negative numbers, the rules flip. Think of it like debt: owing $3 is worse than owing $1, so -3 < -1. The further left on the number line, the smaller the value.

How do I remember which negative number is bigger?

Use the number line trick: whichever number is further to the right is always bigger. Since -1 is to the right of -3, we know -1 > -3.

What if I have to compare many negative numbers?

Does this work for decimals and fractions too?

Absolutely! Whether it's $-2.5$ vs $-1.3$ or $-\frac{3}{2}$ vs $-\frac{1}{2}$ , the same rule applies: further right means bigger.

How can I check my comparison is correct?

Try the addition test: if a > b, then a + (positive number) > b + (same positive number). For example, -1 + 5 = 4 and -3 + 5 = 2, and since 4 > 2, we confirm -1 > -3!
