Integers Order of Operations

In countries like Australia, we use the “BODMAS” or “BOMDAS” Rule for doing maths operations in the correct order.
In the USA, and some other countries, use the “PEMDAS” Rule for doing their maths operations. “Operations” are any of the following: Brackets, Squares, Powers, Square Roots, Division, Multiplication, Addition, and Subtraction. Operations Introduction Consider the following question: 1 + 2 x 5 There are two possible ways of doing this question: the right way, and the wrong way! If you are having trouble thinking about which one is the correct answer, then think about a money sum.
If someone gave you one dollar plus two five dollar notes, then the total would be $11.
It would not be $15. Now consider this next question: 2 + 3 x -4 Again there are two possible ways of doing this question: the right way, and the wrong way. We must follow the “Order of Operations” carefully in Mathematics to arrive at correct answers.   BODMAS Video For countries like Australia that use BODMAS, the following five minute video covers how everything works.
