Math basic concept on subtraction word problems - 1-digit numbers for the first grade. To understand the word problems with different digits combinations read the question carefully and follow the steps provided.
Suppose, a man had 7 apples, he ate 3 of them. How many apples are still left?
Here we know that when 3 things are taken from 7 things there are then 4 things left. Therefore, the answer to the question is 4 apples.
This subtraction sum may be written down in either of the following ways:
7 – 3 = 4
or
We notice that to subtract 3 from 7 is the same as finding what must beaded to 3 to make 7.
This is a good way of doing subtraction sums. Thus, in subtracting 3 from 7 you say in your mind ’3 and how many more make 7?’ The answer is 4.
Worked-out examples on subtraction word problems – 1-digit numbers:
1. There are 4 kites in all. 2 of the kites are crossed out to show that they are being taken away. What number do you get when you start with 4 and take away 2?
To find 4 minus 2, count the kites that are not crossed out.
There
are 2 kites left. When you start with 4 and take away 2, you are left with 2.
So, 4 – 2 = 2
2. There are 5 footballs in all. 3 of the
footballs are crossed out to show that they are being taken away or lost. What
number do you get when you start with 5 and take away 3?
To find 5 minus 3, count the footballs that are not crossed out.
There
are 2 footballs left. When you start with 5 and take away 3, you are left with 2.
So, 5 – 3 = 2
3.
There are 9 ice-creams in all. 3 of the
ice-creams are crossed out to show that they are being taken away or eaten.
What number do you get when you start with 9 and take away 3?
To find 9 minus 3, count the ice-creams that are not crossed out.
There
are 6 ice-creams left. When you start with 9 and take away 3, you are left with
6.
So, 9 – 3 = 6
