Ways to Make a Number Using Subtraction Part 1

Consider the following options:

13 – 4

12 – 2

16 – 7

12 – 3

Let's identify all the correct ways to make number 9.

First check the difference of given numbers in each option by counting back from the bigger number.

Consider the first option.

 

13 – 4 = ?
 

Starting from 13, count back 4.

So, 13 – 4 = 9

 

Now, check the second option.

 

12 – 2 = ?

 

Starting from 12, count back 2.

So, 12 – 2 = 10

 

Now, check the third option.

 

16 – 7 = ?

 

Starting from 16, count back 7.

So, 16 – 7 = 9

 

Now, check the last option.

 

12 – 3 = ?

 

Starting from 12, count back 3.

 

So, 12 – 3 = 9

 

So, the correct ways to make number 9 are 13 – 4, 16 – 7, and 12 – 3.
