|Order of Operations|
This tutorial is designed to help you solve problems correctly by using the 'Order of Operations'. When there is more than one operation involved in a mathematical problem, it must be solved by using the correct order of operations. A number of teachers use acronyms with their students to help them to retain the order. Remember, calculators will perform operations in the order which you enter them, therefore, you will need to enter the operations in the correct order for the calculator to give you the right answer.
In Mathematics, the order in which mathematical problems are solved is
2. Calculations in brackets (parenthesis) are done first. When you have more than one set of brackets, do the inner brackets first.
3. Exponents (or radicals) must be done next.
4. Multiply and divide in the order the operations occur.
5. Add and subtract in the order the operations occur.
Acronyms to Help you Remember
you remember this order?
Does It Make a Difference? What If I Don't Use the Order of Operations?
were very careful when they developed the order of operations.
You can see
that it is absolutely critical to follow the order of operations. Some
of the most frequent errors students make occur when they do not follow
the order of operations when solving mathematical problems. Students can
often be fluent in computational work yet do not follow procedures. Use
the handy acronyms to ensure that you never make this mistake again.
