How to Subtract Numbers without using Number Line?
We can subtract the numbers without using number lines. You must follow the below rules to subtract numbers without the help of number lines.
- To subtract the numbers we need to change the subtraction sign into an addition sign.
- Then, take the inverse of the number that comes after the sign.
- Change the subtracted number sign and add them to find the subtraction of the numbers.
Or,
To subtract one number from another number, the sign of the subtracted number need to change. Then, the sign changed number need to add to the first number.
Subtraction of Numbers without using Number Line Examples
Check out the below examples to find out the subtraction of numbers without using a number line.
Example 1:
Subtract (7) – (2)
Solution:
Given numbers are 7 and 2. Both are positive numbers.
Convert the sign of the subtracted number to perform subtraction.
So, 2 becomes -2.
Now, perform the subtraction between 7 and 2.
7 – 2 = 5.
Therefore, the answer is 5.
Example 2:
Subtract (4) – (-4)
Solution:
Given numbers are 4 and -4. One number is positive and another number is negative.
Convert the sign of the subtracted number to perform subtraction.
So, -4 becomes +4.
Now, perform the subtraction between 4 and -4.
4 + 4 = 8.
Therefore, the answer is 8.
Example 3: Subtract (-7) – (3)
Solution:
Given numbers are -7 and 3. One number is positive and another number is negative.
Convert the sign of the subtracted number to perform subtraction.
So, 3 becomes -3.
Now, perform the subtraction between -7 and 3.
-7 – 3 = -10.
Therefore, the answer is -10.
Example 4:
Subtract (-2) – (-5)
Solution:
Given numbers are -2 and -5. Both given numbers are negative numbers.
Convert the sign of the subtracted number to perform subtraction.
So, -5 becomes 5.
Now, perform the subtraction between -2 and -5.
-2 + 5 = 3.
Therefore, the answer is 3.
