minus sign
You do it wrong. With out order of operations, the same math problem could have several different answers. In math, there is only one answer.
A number by itself is meaningless. Symbols and labels add meaning in math. Symbols in math are used to represent different operations, and/or add descriptions. There are many different symbols each which have their own purpose. Some symbols have different purposes in different types of math.
It is convenient for different people to agree on the standard order of operations. This saves complicated explanations.
There are 4 basic maths operations: addition, subtraction, multiplication and division.

The basic operations are union and intersection.
I want to know [what is the order of operations in math?]
The basic operations are union, intersection and complement.

An example of three different operations in math includes addition, subtraction, and multiplication. For instance, if you have the numbers 5 and 3, you can add them to get 8 (5 + 3), subtract to get 2 (5 - 3), or multiply to get 15 (5 × 3). Each operation serves a unique purpose in calculations and problem-solving.
