there's a phrase you can use to remember the order of operations: Please Excuse My Dear Aunt Sally.
it breaks down like this:
P stands for Parenthesis, complete any operations that are in parenthesis (includes brackets, braces and absolute value).
E stands for Exponents, clear any exponents next (includes square roots).
M stands for Multiplication, complete any multiplication problems (from left to right) in the problem.
D stands for Division, complete any division problems (from left to right) in the problem.
A stands for Addition, complete any addition problems (from left to right) in the problem.
S stands for Subtraction, complete any subtraction problems (from left to right) in the problem.
This order of operations must be followed because if it's not then you can come up with all sorts of wrong answers.
For Example: 5+6*2=? or 5 plus 6 times 2
first: Multiply 6*2=12
now you have: 5+12=?
second: Add 5+12=17
Therefore your final answer for 5+6*2=17
There are different rules for different operations.

There are many. There are those that deal with the four basic binary operations, then there are rules governing exponents and logarithms.

The set of real numbers is closed under addition, subtraction, multiplication, and division (except that you cannot divide by zero). By closed, this means that if the two numbers in the operation are both real numbers, the result of the operation will always be a real number. Dividing by zero is undefined (for all practical purposes)
study it and its value
When people started classifying numbers in different ways Some numbers were grouped together and called Real numbers. Solutions that would create Imaginary numbers were simply explained away as impossible, later the rules for working with these numbers, but, even though they are not considered Real numbers some math operations will create Real number answers.
Complex math covers how to do operations on complex numbers. Complex numbers include real numbers, imaginary numbers, and the combination of real+imaginary numbers.

There are infinitely many operations. Any rule that takes one or more real numbers as input and outputs one or more real numbers is an operation involving real numbers. So addition, subtraction, multiplication, division, squaring, doubling, cube-rooting, trigonometric functions, multiplying a real vector by a matrix of the appropriate size, are all examples.
Complex numbers extend the concept of real numbers by introducing an imaginary unit, denoted as "i." Real numbers can be considered a subset of complex numbers with the imaginary part equal to zero. Complex numbers include both a real and imaginary component, allowing for operations like addition, subtraction, multiplication, and division.
