Common Mistakes Students Make with BODMAS in Algebra
Using the right order of operations is really important when solving math problems. This method is often remembered with the acronym BODMAS (or BIDMAS).
Many students, especially in Year 7, find this tricky. In fact, research shows that almost 40% struggle with it. This can lead them to get the wrong answers.
Ignoring Parentheses: Some students forget to do the calculations inside parentheses first. This mistake can cause issues. For example, if you see (3 + 5 \times 2), some might think the answer is (16), when it should actually be (13).
Getting Exponents Wrong: Exponents can be confusing too. Sometimes, students overlook them or don't calculate them right. For instance, if they look at (2^3 + 1), they might incorrectly think it equals (3) instead of calculating it correctly as (8 + 1 = 9).
Mixing Up Multiplication and Division: Students sometimes get confused about the order of multiplication and division. They may do these calculations from left to right instead of following BODMAS rules.
Not Understanding Addition and Subtraction Order: Addition and subtraction should also be done carefully. Many students treat them equally and forget to process them from left to right. For example, in (10 - 2 + 3), they should do the math as (8 + 3 = 11), not change the order of the numbers.
By helping students notice and fix these common mistakes, teachers can boost their understanding of math operations. This, in turn, can lead to better performance in algebra.
