What is difference in mathematics? Mathematics can be quite challenging to many people, yet applying math helps to solve most of our problems. For example, we usually need to compare price, distance, etc. This is when we need to apply math and find the difference.
So, how to find and apply it? Let’s stay tuned to figure out things!
What Is The Difference In Mathematics?
The difference between two things is usually used to explain what these things do not have in common. However, things work differently in math. In mathematics, difference implies the distance of the two numbers on a number line.
For example, the distance on a number line between 30 and 25 is 5; hence the difference between 30 and 25 is 5.
To put it simply, the outcome of removing 1 number from others is a difference. Subtraction is another name for the act of determining the difference.
Other terms for the difference in mathematics include minus, less, and take away.
You should also remember the three key terms in this process: subtrahend, minuend, and difference.
- Minuend: The amount left from when the subtrahend is removed referred to as the minuend.
- Subtrahend: The deducted number is referred to as the subtrahend.
- Difference: Difference is this subtraction’s outcome.
(-) is the symbol for the difference in mathematics. The following is a formula to determine the difference between two numbers:
Minuend – Subtrahend = Difference
Although all of these applications of the term difference involve the same notion of difference, they might appear to be quite different in practice.
- An equation with a difference between the values of two variables is called a difference equation.
- The numerator of the calculus fraction known as the difference quotient is the difference between two functions.
- The polynomial of a2 – b2 is known as a difference of squares because it determines the difference between two squares a2 and b2.
Is Difference Subtraction?
The difference is the same as subtraction; the answer is almost. The mathematical operation of subtracting is similar to the mathematical process of determining the difference, but the two terms have a different outcomes.
While the result of the subtraction can be both positive and negative, the outcome of difference can only be positive because difference refers to the distance between two numbers, so it can not be negative.
Calculate the absolute value to determine the positive distance if the difference after computations is negative. This is also why you need to remember which number is subtrahend and which is the minuend.
Once again, the value from which the other value is being deducted is called the minuend. On the other hand, the subtrahend is the amount being removed. The minuend is bigger than the subtrahend in the mathematical process of determining the difference.
For example, to find the difference between 15 and 12, you need to figure out that 15 is the larger value. Therefore, to determine the difference, subtract 12 from 15, and you will get three as the difference: 15 – 12 = 3.
How To Find Differences In Mathematics?
Find the Difference between Natural Numbers and Whole Numbers
If you want to find the difference between two natural or whole numbers, remove the smallest value from the larger one. You can calculate in your head or follow the basic steps below:
- Arrange the items in ascending place value order.
- Start subtracting each number from right to left.
For example, to calculate the difference between 200 and 55, arrange the numbers in ascending order of their place values, and you will get 145 as the difference.
Find the Difference Between Decimal Numbers
Examining the dissimilarity between 2 decimal numbers is not very different from that of a natural or whole number. You only need to note down the decimal point, which creates the difference between natural and decimal numbers.
The steps to calculate the difference include:
- Change two numbers into similar decimals.
- Then, line them up by placing the decimal numbers one below the other, the decimal point underneath the decimal point, with the ones below the ones, the tenth digit beneath the tenth digit and the hundredth digit beneath the hundredth digit, and so on.
- As with the natural numbers, subtract and borrow where required.
- After the decimal point in the decimal numbers, place the decimal point in the difference.
For instance, to estimate the difference between 9.567 and 6.5, we need to give them all the same amount of decimal places, which means converting each decimal.
6.5 becomes 6.500 as a result. The computation may now be done as: 9.567 – 6.500 = 3.067. Therefore, there is a 3.067 discrepancy between these figures.
Find the Difference Between Fractions
To determine the difference between two fractions, you will first have to simplify these numbers and find their smallest common denominator. Here are the detailed steps:
- Simplify the fractions if needed so you can do these steps more easily.
- Determine the denominators of the fractions. Check whether or not the fractions’ denominators are similar. Move to step 5 in case of similar denominators; otherwise, skip to step 3.
- Calculate the smallest common multiple of the denominators if the denominators are different.
- Create comparable fractions for each function using a similar denominator as the smallest common multiple determined in the last step. Rewrite the fractions into their corresponding fractions with denominators equal to the smallest common multiple.
- As you’ve got the same fractions, finish subtracting their numerators like you would for a like fraction. Simplify the result if necessary.
For example, the quiz asks you to find the difference between 15/20 and 1/2. Then, simplify 15/20 and 1/2 to the simplest forms to get 3/4 and 1/2. Now turn them into the same smallest common multiple, 4, and we get 3/4 and 2/4. Take away 2/4 from 3/4, so we have the answer is 1/4.
Using Difference For Comparison
We may also compare several sorts of numbers using the difference to determine how they differ. Let’s examine the distinctions between key mathematical words.
Difference Between Natural Numbers and Whole Numbers
Natural numbers and whole numbers might make beginners’ mistakes sometimes because they are almost similar. However, the key lies in the number zero ( 0 ), so you should clarify it.
In the case of natural numbers, they are referred to as the fundamental counting numbers, and they start from 1. The symbol for natural numbers is the letter N.
On the other hand, whole numbers are the collection of natural numbers, but they begin with the number 0. W is used to represent whole numbers. The only differences between natural and whole numbers here are the number zero and the symbol of each. Both are quite easy to remember.
Difference Between Fractions and Rational Numbers
Like natural and whole numbers, fractions and rational numbers are similar. Yet, it is not difficult to tell these types apart.
All fractions are rational numbers, and they are expressed as a/b, where a and b are whole numbers, and b must not be 0. Examples of fractions can be 1/5, 3/4, 10/19, etc.
In terms of rational numbers, all rational numbers are not fractions. They are performed as p/q, where p and q are integers and q must not be 0. Rational numbers are figures like 3/-8, 6/5, and -3/4.
Difference Between Area and Perimeter
The other two terms that usually cause misunderstandings are the terms area and perimeter.
An enclosed shape’s area in a two-dimensional plane is referred to as the area. The unit of measurement of the area is the square unit. We can take a playground area as an example, so we have the playground’s area as the whole surface that we can run around.
On the contrary, the circumference of a closed form is measured by its perimeter. The perimeter is quantified in units. Once again, take the playground as an instance; its perimeter is the whole outer boundary length of the playground.
What Are The Key Facts About Difference In Mathematics?
So, there are some key matters about the difference in mathematics that you should bear in mind.
- The outcome of subtracting one integer from another is the difference. Subtraction is another name for the act of determining the difference, but it is no different.
- The icon representing the difference between two numbers is ( – ). The formula to determine the difference between two numbers is Minuend – Subtrahend = difference.
- We arrange the values vertically in order of their place values to determine the difference between two or more whole numbers or natural numbers. The numbers are then subtracted, beginning at the position of one.
- We turn each function into an equivalent fraction with the same denominator to calculate the difference between two or more fractions. The smallest common multiple of the denominators is used to accomplish this. After that, deduct their numerators to get the results.
- Write the decimal numbers down, one figure under the other, then align the decimal points to get the difference of two or more decimal values.
Change the provided decimals to equivalent ones. Make sure the addends are arranged so that the same-place digits are all in a similar column. As we often do with addition, subtract the values from the right.
