The Number Line with Signed Numbers: Missing formula

All negative numbers appear on the number line to the left of the number 0.

If we draw a number line, we can see that to the right of zero are positive numbers, and to the left of zero are negative numbers:

Therefore, the answer is correct.

True.

$3.98$ and $+3.98$ are two ways of writing the same number.

Indeed, both forms are identical since a number without a sign will be positive, as in the case of 3.98

If there is a plus sign before the number, the number is necessarily positive, as in the case of +3.98

Therefore, the answer is correct.

True

Every positive number is greater than zero

The answer is indeed correct, any positive number to the right of zero is inevitably greater than zero.

True

-2 < 0

Since every negative number is necessarily less than zero, the answer is indeed correct

True

4\frac{1}{2} < -5

The answer is incorrect because a negative number cannot be greater than a positive number:

4\frac{1}{2} > -5

Not true

The minus sign can be omitted

The sign cannot be omitted as it determines whether the number will be negative or positive.

Not true

-4>-3

The answer is incorrect because neative 3 is greater than negative 4:

-4 < -3

Not true

5 < -5

As per the fact that there cannot be a situation where a negative number is greater than a positive number, the answer is incorrect.

Not true

Does the number $-6$ appear on the number line to the right of number $2\text{?}$

If we draw a number line, we can see that the number minus 6 is located to the left of the number 2:

Therefore, the answer is not correct.

No

-4>A

We begin by locating the numerical representation of the letter on the number line:

$A=-5$

We then compare the two numbers:

-4 > -5

It appears that the answer is indeed correct.

True

B > A

Let's locate the numerical representation of the letter on the number line:

$B=-4$

$A=-5$

Now let's place:

-4 > -5

It appears that the answer is indeed correct.

True

C > E

Let's locate the numerical representation of the letter on the number line:

$C=-3$

$E=-1$

Now let's place:

-3>-1

It appears that the answer is not correct.

Not true

K < A

We must first identify the numerical representation of the point on the number line:

$K=5$

$A=-5$

Now we compare the two numbers:

5 < -5

It appears that the answer is not correct.

Not true

E < C

Let's locate the numerical representation of the point on the number line:

$E=-1$

$C=-3$

Now let's place:

-1 < -3

It appears that the answer is not correct.

Not true

C > E

We will locate the letters on the number line and see which numbers represent them:

$C=-3$

$E=-1$

We will plot and see that:

-3 > -1

Therefore, the expression is not correct.

Not true

B>A

We first locate the numerical representation of the letter on the number line:

$B=-4$

$A=-5$

We compare their two values:

-4 > -5

It appears that the answer is indeed correct.

True

-4 > A

We will locate the point on the number line and see which number it represents:

$A=-5$

We will plot and see that:

-4 > -5

Therefore, the expression is correct.

True

$-3=-3$

True
