Subtraction is a mathematical operation that represents the operation of removing objects from a collection. It is signified by the minus sign (−). For example, in the picture on the right, there are 5 − 2 apples—meaning 5 apples with 2 taken away, which is a total of 3 apples. Therefore, 5 − 2 = 3. Besides counting fruits, subtraction can also represent combining other physical and abstract quantities using different kinds of objects including negative numbers, fractions, irrational numbers, vectors, decimals, functions, and matrices.
Subtraction follows several important patterns. It is anticommutative, meaning that changing the order changes the sign of the answer. It is not associative, meaning that when one subtracts more than two numbers, the order in which subtraction is performed matters. Subtraction of 0 does not change a number. Subtraction also obeys predictable rules concerning related operations such as addition and multiplication. All of these rules can be proven, starting with the subtraction of integers and generalizing up through the real numbers and beyond. General binary operations that continue these patterns are studied in abstract algebra.

You will learn about "Basic Subtraction" in this video. We subtract to find out how many things are left after some of them are taken away. The sign used for subtraction is - and is read as minus. Look at these 5 bananas. 2 of them are taken away. Now, how many bananas are left? As 2 is taken away from 5, we subtract 2 from 5. 5 – 2 = 3. Hence, 3 bananas are left. There are 7 sticks on the ground. If 3 of them are taken away, 4 sticks will be left. Therefore, 7 – 3 = 4. Hence, subtraction is used to find the difference between two numbers.

This looks at how to do simple subtraction in maths. No tricks, no fuss. This is one of the most basic things in maths - yet as a senior level maths teacher I am astounded how many people lack this ability - and as such they struggle throughout their school years at maths. Addition, subtraction, division and multiplication - these are the most important thing anyone should know in maths , yet a large number of people who still are yet to attain this skill! Practice this lesson!
Two too many. Take one. Subtract. Leave none
But don't set your hopes too high
Or you'll wind up like the other guy
There is another self. I am not alone
For what I have done
You can't blame it all on me
A kleptomaniac
You'll never get
Your best prize back
Thou shall not kill
Though shall steal
Though cannot take
What I have not
What we learned today
Useless rights abused
And thrown away
Greed's looking at me, my mind can't remember
He pulled a quick one, cleaned them out
And clues he left none
I never could write a book on trust
Even when my head got fucked
Oh no, I would never blame it on us
If you want the fact
