Subtraction is a numerical operation that speaks to the operation of expelling articles from a gathering. It is meant by the less sign (−). For instance, in the photo on the privilege, there are 5 − 2 apples—which means 5 apples with 2 taken away, which is an aggregate of 3 apples. In this manner, 5 − 2 = 3. Other than checking organic products, subtraction can likewise speak to consolidating other physical and theoretical amounts utilizing various types of articles including negative numbers, portions, silly numbers, vectors, decimals, capacities, and grids. Subtraction takes after a few imperative examples. It is anticommutative, implying that changing the request changes the indication of the reply. It is not acquainted, implying that when one subtracts more than two numbers, the request in which subtraction is performed matters. Subtraction of 0 does not change a number. Subtraction likewise obeys unsurprising principles concerning related operations, for example, expansion and duplication. These principles can be demonstrated, beginning with the subtraction of whole numbers and summing up through the genuine numbers and past. General parallel operations that proceed with these examples are concentrated on in conceptual variable based math.

Subtraction Decimals:

To subtract decimals, follow these steps:

  1. Write down the two numbers, one under the other, with the decimal points lined up.
  2. Add zeros so the numbers have the same length
  3. Then subtract normally, remembering to put the decimal point in the answer

Example: Subtract 0.03 from 1.1

Line the decimals up:

 

 

1.1

 

 

0.03 

 

 

 

 

"Pad" with zeros:

 

 

1.10

 

 

0.03

 

 

 

 

Subtract:

 

 

1.10

 

 

0.03

 

 

 

1.07

Answer: 1.07

So, that was just like 110 − 3 = 107, but with the decimal point in a different position

Example: Calculate 7.005-0.55

Line the decimals up:

 

 

7.005

 

 

0.55

 

 

 

 

"Pad" with zeros:

 

 

7.005

 

 

0.550

 

 

 

 

Subtract:

 

 

7.005

 

 

0.550

 

 

 

6.455

Answer: 6.455

Subtracting Fractions:

There are 3 simple steps to subtract fractions 

Step 1. Make sure the bottom numbers (the denominators) are the same 

Step 2. Subtract the top numbers (the numerators). Put the answer over the same denominator. 

Step 3. Simplify the fraction (if needed). 

Example 1:

Step 1. The bottom numbers are already the same. Go straight to step 2.

Step 2. Subtract the top numbers and put the answer over the same denominator: 

  =     =  

Step 3. Simplify the fraction:

=

(If you are unsure of the last step see Equivalent Fractions.) 

Example 2: 

Step 1.To make the bottom numbers the same, multiply the top and bottom of the first fraction (1/2) by 3
And now our question looks like this:

 Step 2. Subtract the top numbers and put the answer over the same denominator:

= =

Step 3. Simplify the fraction:

=
