Negative Whole Numbers

Introduction :
Negative numbers are defined as the numbers that less than zero. It is always an opposite of the positive numbers. A negative whole number means negative numbers which consist of all negative integer numbers. We can add, subtract, multiply and divide by using the negative whole numbers. For example 0, 1, 2, 3… and -1, -2-, 3… etc

Examples of Negative Whole Numbers:

Negative whole numbers example 1:

Simplify (-120) + (-250)

Solution:

Given problem is (-120) + (-250)

We can add the given negative whole numbers by using the following methods:

Positive * negative = negative

In the given problem, first term as -120 and then the second term as + (-250) = -250

Negative + negative = negative

Therefore, -120 + -250= -370

So we get the final result as negative number.

Answer: -370

Negative whole numbers example 2:

Simplify (-200) - (-500)

Solution:

Given problem is (-200) - (-500)

We can subtract the negative whole numbers by using the following methods:

Negative * negative =positive

In the given problem, first term as -200 and then the second term as - (-500) = + 500

But here negative + positive = positive. Because of positive number (500) is larger than negative value (200).

That is, -200 + 500= 300

Here we get the final answer is positive. Understanding Is pi a Rational Number? is always challenging for me but thanks to all math help websites to help me out.

Answer: 300

Negative whole numbers example 3:

Simplify (-400) * (-100)

Solution:

Given problem is (-400) * (-100)

We can multiply the negative whole numbers by using the following methods:

Negative * negative = positive

But here we can just multiply the whole numbers. Then we get

-400 * (-100) = 40000

Answer: 40000

Negative whole numbers example 4:

Simplify (-1200) / (-300)

Solution:

Given problem is (-1200) / (-300)

Here we are dividing the above whole numbers.

Negative / negative = positive

Therefore we get the positive answer.

That is, -1200/-300

Here minus sign are canceled on both numerator and denominator.

Then we get,

1200/300

1200 is 4 times of 300

1200/300= 4

Therefore we get the final answer is 4.

Answer= 4

Practice Problems of Negative Whole Numbers:

Simplify the following problems:

(-100) + ( -50)
(- 120) – ( -60)
( -30) * (-40)
(-400) / (-50)
Answer keys:

-150
-60
1200
8
