The order in which you compute multiplication and division is determined by which one comes first, reading from left to right. By the way, all three acronyms are correct. The second set indicates multiplication. This can be written mathematically as an bn = (a b)n. When the exponents with different bases and different powers are multiplied, each exponent is evaluated separately and then multiplied. The order of operations is important because it guarantees that people can all read and solve a problem in the same way. It stands for Parentheses, Exponents, Multiplication/Division, Addition/Subtraction. If there are no brackets, start solving from order or of followed by Division or multiplication (whatever comes first from left to right) then by addition or subtraction (whatever comes first from left to right). These expressions should be calculated first before the operations of multiplication, division, addition and subtraction. Sometimes subtract before addiing! According to the BODMAS rule, we must multiply first and then add." This means that you don't just solve math problems from left to right; rather, you solve them in a predetermined order that's given to you via the acronym PEMDAS.
