Math Negative And Positive Numbers – Numbers greater than zero are called positive numbers, and numbers less than zero are called negative numbers. This means they fall on both sides of the number line. However, just because they’re on the same page doesn’t mean they follow the same rules! Keep reading for a list of basic rules for using positive and negative numbers in math.
When working with positive and negative numbers, you use the rules for signed numbers (numbers with a positive or negative sign). Also known as signed number operations, these steps can help you avoid confusion and solve math problems as quickly as possible—and correctly.
Math Negative And Positive Numbers
Follow these rules to determine the best way to add, subtract, multiply, and divide positive and negative numbers. Remember that if there is no + or – sign, the number is positive.

When you add two numbers together and they have the same sign (two positive or two negative numbers), add the numbers and keep the sign. For example:
Note that equations with two positive numbers have positive sums and equations with two negative numbers have negative sums. If you use a number line to solve a problem, adding two positive numbers goes further on the positive side and adding two negative numbers goes further on the negative side.
If you add positive and negative numbers together, subtract the smaller number from the larger number and use the sign for the larger number. For example:
As you can see, adding numbers with different signs is really a form of subtraction. When you use a number line, your total is closer to zero.

Subtracting positive and negative numbers means that you are adding the opposite numbers or the inverse additive. Change the minus sign to addition and change the next sign to the opposite. Then follow the steps to add. For example:
A good tip is that whenever you see a negative sign and a minus sign together, as in 9 – (-7), immediately convert them to positive signs. The negative signs cancel each other out, and the equation becomes a summation problem.
Multiplication and division seem to be more complicated than addition and subtraction, but in fact they are much simpler. The rule for multiplying positive and negative numbers with the same sign (two positive or two negative) is that the product is always positive. For example:
The same rule applies to division. When a number is divided by another number with the same sign, the quotient (answer) is positive. For example:
Positive And Negative Numbers
Why is multiplying or dividing two negative numbers always a positive number? Like subtracting negative numbers, these operations turn negatives into opposites (inverses). Basically, you’re subtracting a negative number multiple times – and as you can see above, subtracting negative numbers results in a positive equation.
When you multiply a positive and a negative, the product is always negative. It doesn’t matter what order the characters are in. For example:
In all these cases, you must first multiply or divide the numbers. Then decide whether the product or quotient is positive (two positive or two negative in the equation) or negative (one positive and one negative in the equation).
Another way to think about adding positive and negative numbers is to look at the signs in a sequence. Two identical characters in a row (++ or –) means you’re adding numbers, while two different characters in a row (+- or -+) means you’re subtracting numbers. For example:

This method follows the same rules as above, but it can help you solve the problem faster if you want to detect the signs beforehand. Once you conceptually understand positive and negative numbers, you can decide which method works best for you.
When you know the basics of mathematics and its rules, the whole mathematical world is open to you. Unlike other subjects, math is not nuanced or open to interpretation – it is what it is! If you want more math practice, check out the steps to long division problems (with examples). You can also review different types of math chapters before your next math assignment. Many people think that mathematics is a difficult subject. One must ask about the use of learning mathematics and the real applications of mathematics. Mathematics is everywhere, as is the meaning of numbers and their connection to everyday life. Mathematics is all about numbers, and numbers can be grouped into different types of numbers, such as integers, whole numbers, real numbers, complex numbers, rational numbers, irrational numbers, and many other types.
All negative numbers have a value less than zero. Negative numbers are used with a minus sign or dash (-) along with the number. On a number line, negative numbers are numbers that are represented to the left of the origin (zero) and their values are less than zero.
It may be strange to notice that a number is less than 0. Because we often think that zero means nothing. For example, if you have 0 pens in your drawer, you have no pens. Nothing left. It is hard to imagine that there is less than nothing in this case. But in real life there are situations when you use numbers less than zero. Some of their real applications are shown below.

Negative numbers are often used to describe credit in the banking system. A negative bank balance means the money is overdrawn. So every time someone owes money, it is represented by a negative amount of money.
An elevator or elevator is a vertical conveyance that moves people or goods between floors of a building. Generally, in buildings, the ground floor is considered 0, so moving to other floors below the ground floor, such as a basement or parking space, is indicated by negative numbers/integers (eg -1, -2, – 3).
Sea level (or mean sea level; MSL) is the average level of Earth’s oceans. This surface water elevation serves as a reference point for measuring elevations above or below it. The elevation or depression of a geographic location is its height above or below sea level. Geographic locations below sea level are represented by negative numbers (eg -100 feet MSL)
Various games or sports use negative numbers when calculating points/points or giving a penalty. If you answer the quiz wrong or lose the game, you may lose points (such points are considered negative numbers). In addition, some sports, such as golf, use negative numbers to calculate scores.

Example: 1) During the night the temperature dropped from 5 ºC to -14 ºC. By how many degrees did the temperature drop?
In self-paced learning, you are likely to forget concepts. – you learn the application visually and you will be surprised by the results.
Negative numbers are commonly used to describe freezing point temperature, credit/payment money, height above/below sea level, elevator level when below ground level, as punishment in quizzes/games, etc.
We use negative numbers to describe a lack of quantity or a reduction/decrease in quantities. Negative numbers are commonly used to describe freezing point temperature, value of money, height below sea level, elevator level when below ground level, negative grades in exams, as punishment in quizzes/games, etc.

Negative and positive numbers are used in real life to describe the distance from a reference point. For example, in an elevator, ground level is considered 0, and floors above ground level are marked with positive numbers as a reference point. The layers below the ground are indicated by negative numbers.
Integers are commonly used to represent temperature above/below freezing point, debit/credit of money, geographic level above or below sea level, elevator level when above or below ground level, bonus and penalty in quizzes/games etc.
Yes, 0 zero is a real number. Real numbers can be positive or negative and include the number 0. Positive and negative numbers are two broad categories of numbers used in mathematics and also in everyday transactions such as managing money or measuring weight.
There are rules for adding, subtracting, multiplying and dividing positive and negative numbers. In general, it is easier to perform operations on negative numbers if they are enclosed in parentheses to keep them separate. Number lines can also make positives and numbers easier to understand.

When adding or subtracting positive and negative numbers, the sign of the answer depends on whether the signs are the same or which number has a greater value.
Adding positive and negative numbers is easy when both numbers have the same sign. Just find the sum of the numbers and hold the sign. For example:
Find the sum of a positive and negative number by subtracting the smaller number from the larger number. The sign is a greater number sign.
The rules for subtraction are similar to the rules for addition. In the case of two positive numbers, if the first number is greater than the second, the result is the second positive number.
