Lets start at the beginning. If you dont you will failin solving the equation anyway. In mathematics the order of operations define the priority in which complex equations are solved.
When you are faced with a mathematical expression that has several operations or parentheses the solution may be affected by the order in which you tackle the operations.
Adding 4 4 is great but more useful is the ability to perform math operations on answers provided in the survey. For example in mathematics and most computer languages multiplication is granted a higher precedence than addition and it has been this way since the. 12 4. To help students in the United States remember this order of operations teachers drill the acronym PEMDAS into them.
