If you want to have a look what happened last time we discussed this ...Mr Davis 97 said:To what extent is the PEMDAS order of operations convention, and to what extent is this convention significant? For example, how would math change if we stipulated that ##1+2*3 = 3*3 = 9##? Would it be the same or would it be completely different?
The convention of order of operations is a set of rules that determines the sequence in which mathematical operations should be performed. It is used to ensure a consistent and unambiguous interpretation of mathematical expressions.
The rules of the convention of order of operations are as follows: 1) Perform operations within parentheses first, 2) Perform multiplication and division from left to right, 3) Perform addition and subtraction from left to right.
The convention of order of operations is important because it allows for a standardized way of solving mathematical expressions, ensuring that the same result is obtained regardless of who is solving the problem. It also eliminates ambiguity and confusion when evaluating complex expressions.
There are certain situations where the convention of order of operations may not apply, such as when using exponential or logarithmic functions. In these cases, it is important to follow the specific rules for evaluating those types of functions.
A common mnemonic device to remember the convention of order of operations is PEMDAS, which stands for Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction. Another helpful tip is to remember that multiplication and division have the same priority, as do addition and subtraction, and should be performed from left to right.
