Here is an example. Simplify 20 16 4. Then add. The presence of multiple brackets may cause confusion and we may get the wrong answer. There are no brackets or orders so start with division and multiplication. Over time, mathematicians have agreed on a set of rules called the order of operations to determine which operation to do first. If you have several operations of the same priority then you work from left to right. If there is no bracket, then the next precedence will be division or multiplication (as both division and multiplication have the same order of preference) and if multiplication comes first in the mathematical expression from left to right. Give students a few more examples, showing an expression with and without parentheses. The four operations are addition, subtraction, multiplication and division. Practice questions. "@type": "Question", We start with the M ultiplication and D ivision, working from left to right.
