Introduction
The value of a number becomes less when you subtract any number from it. Subtraction worksheets on are designed in a way that provide useful insights into this topic and help students get more exposure to a variety of sums.
Let us consider an example now for a better understanding. If you have 10 Apples and remove 5 of them, you will have 5 Apples left.
From the same example, we can write it in a mathematical equation as 10 – 5 = 5.
-
You can read it as ten minus five is equivalent to five. (A mathematical equation is essentially a math sentence that uses numbers and symbols.)
-
We use two symbols when we do the subtraction, that is – and =
-
The minus sign (-) indicates that one quantity is subtracted from the other.
-
Basically, we subtracted 5 apples from a Lot of 10 apples.
What is Subtraction?
As discussed earlier, Subtraction in Mathematics means taking away certain things from a group. In other words, we can also say that it is the method of removing objects from a group. The words “Minus”, “Less”, “Difference”, “Decrease”, “Take Away” and “Deduct” mean that one quantity is to be subtracted from another quantity.
Facts:
-
Small numbers can be subtracted horizontally and big numbers can be subtracted vertically.
-
Subtraction sums are just the opposite of addition sums.
-
Subtracting zero from a number does not change the number’s value.
-
1 subtracted from a number gives the number’s predecessor as the difference.
-
The number from the other number is deducted is called the minuend. The number subtracted is called the subtrahend, and the answer is nothing but their difference.
For example:
Subtraction Problems
1. Pakistan Scored 250 Runs and India Scored 150 Runs in an International Cricket Match. How Many More Runs Does India have to Score Equal to Pakistan?
Ans: Runs scored by Pakistan: 250
Runs scored by India: 150
Now, if we perform subtraction, i.e., taking 150 from 250, we get
So, India must score 100 runs to be equal to Pakistan’s runs.
2. 2 Months Back, the Pet Cow of Mahima, Weighed 25 Kgs. He is Weighing 45 Kgs Now. What has She Gained in Weight?
Ans: Weight 2 months back: 25Kgs
Weight at the moment: 45Kgs
The difference between both weights is the present weight.
So, if we deduct 25 from 45, we get,
The weight gain in 2 months is 20Kgs.
Subtraction of Larger Number from Small Number:
Remember the terms switch and negate when you subtract a larger number from a smaller number. That is, change the order of the two numbers to the same level and make the subtraction as you would normally do. But keep a minus symbol at the end.
Example: To find 5-8, you can just switch the order of two numbers, and perform 8-5, which equals 3; then you can negate the result to get –3. So, 5-8 will be – 3.
Remember not to get confused by the minus sign. If a minus sign is put between two numbers, this indicates the first number minus the second. But it does mean that this number is a negative one when you add it to the front of a specific number.
Subtraction with Decimal Numbers
Take these steps to delete decimals:
-
Write down the two numbers with decimal points in alignment one below the other.
-
Add zero so the length of the numbers is the same.
-
Then normally subtract. But remember to insert the decimal point in the answer.
Subtraction puzzles: Fact family subtraction
A number fact which is made of three numbers called the fact family.
Suppose if have 8-5
-
8 – 5 = 3
-
The above equation can also be written as 8 -3 = 5 and 5+3=8
-
Here 3,5 and 8 are members of the fact family.
Conclusion:
Our choice of a subtraction method depends on the numbers involved. In order to solve problems with subtraction, we can use addition as subtraction in the inverse process. Subtraction is closely associated with addition.
