Because they can both have variables.
Operations
Order of arithmetical operations is called BIDMAS meaning Brackets, Indices, Division, Multiplication, Addition followed by Subtraction.
Subtraction
If you are asking 'in what order are arithmetic operations performed'; One useful mnemonic is BEDMAS. This order is Brackets, Exponents, Division, Multiplication, Addition, and Subtraction. Sometimes called Order of Operations.
It is the "additive identity".
Two operations that undo each other are called inverse operations. Examples are addition and subtraction, or multiplication and division.
It is called the "inverse" operation. (*The term inverse is specifically used for multiplication and division, where the inverse of x is 1/x.) Inverse operations: addition / subtraction multiplication/ division square / square root cube / cube root
Operations
Binary operations.
Mathematical processes or operations
The inverse operation of addition would be subtraction. The inverse operation of subtraction would be addition. The inverse operation of multiplication is division and the inverse operation of division is multiplication. It is called the inverse operation because you are reversing the equation. If you add, subtract, multiply, or divide the same number on each side of the equation, then the equation would still be true. As long as you are doing the same thing on BOTH side of the equation. The reciprocal is used for dividing fractions. All you have to do for finding the reciprocal of a fraction is flip the fraction. Ex: The reciprocal of 1/4 is 4. The reciprocal of 5/8 is 8/5. You can check by multiplying the two fractions. It will equal to one if you did it right. I hope this helped a little bit.
In some respects they are the same in others they are not. At a simple level, multiplication is simply repeated addition so that the two operations are the same. However, an inverse operation can be defined on the set of rational or real numbers for addition (it is called subtraction) but not in its entirety for multiplication (division by zero is not defined).
Yes and the other two basic operations are multiplication and division

Inverse operations
Subtraction
An inverse operation is an operation that reverses the effect of the original operation. For example, addition and subtraction are inverse operations. 2 add 5 is 7, subtract 5 is 2. The subtraction of 5 reversed the effect of adding 5. Multiplication and division are also inverse operations. Two functions f and g are inverse if f(g(x)) = g(f(x)) = x.
