The number 4 is an integer (the Number 4.1 is a real number and not an integer)
The number 2 is an integer (the number 2.9 is a real number and not an integer)
4-2 = 2
4+2 = 6
The above are examples of how the integers 4 and 2 can be added or subtracted.
It is important to add and subtract integers: to get a new integer value in mathematics .
you can add subtract multiply and divide them.
to subtract an integer, add its opposite or additive inverse.
Because otherwise you would only know how to subtract and add with the same integers. Not a particularly useful skill unless just those integers turned up!
add, subtract, multiply, divide
When adding negative integers, you subtract. (2+-1=1) When subtracting negative integers, you add. (2--3=5)
When you add, subtract, or multiply integers, you get integers. When you divide one integer by another one, you may or may not get an integer.
+2 + -1= 1
Integers
Integers do not have sides so the question does not make sense.
add subtract divide multiplication
You arrive at a resultant, the resultant depends on the operation carried out.
