The order of operations is important because **it guarantees that people can all read and solve a problem in the same way**.

The BIDMAS rule is an alternative acronym to BODMAS to help remember the order of operations. The only difference is that **there's an I instead of O**. The meaning is the same. Bidmas is the term more commonly used in primary schools today.

- **Because multiplication is more powerful than addition**. We always do what is more powerful first. Any other ideas to add to that? - It's repeated addition so we can break down to an easier way to understand.

When is the Bodmas Rule not Applicable? BODMAS rule is **not applicable to equations**. It is applicable to mathematical expressions having more than one operator.

The order of operations is important because **it guarantees that people can all read and solve a problem in the same way**.

**The following formulas help to solve arithmetic progression problems:**

- Common difference of an AP: d = a
_{2}- a_{1}. - n
^{th}term of an AP: a_{n}= a + (n - 1)d. - Sum of n terms of an AP: S
_{n}= n/2(2a+(n-1)d)

Using Parentheses ( )

Note that per the order of operations, you'd work what's in the parentheses first, next, **calculate numbers with exponents, and then multiply and/or divide, and finally, add or subtract**.

**PhotoMath is a free mobile app** that can read and solve mathematical expressions using your smartphone camera in real time. PhotoMath may sound like it is simply helping kids cheat, but the app also provides a step-by-step guide showing how each of the problems are solved.

The order of operations can be remembered by the acronym PEMDAS, which stands for: parentheses, exponents, multiplication and division from left to right, and addition and subtraction from left to right. First, **simplify the parentheses**. Then, do exponents. Next, multiply.

Some people got 16 as the answer, and some people got 1. The confusion has to do with the difference between modern and historic interpretations of the order of operations. **The correct answer today is 16**. An answer of 1 would have been correct 100 years ago.

Remember in seventh grade when you were discussing the order of operations in math class and the teacher told you the catchy acronym, “PEMDAS” (**parenthesis, exponents, multiplication, division, addition, subtraction**) to help you remember? Memorable acronyms aren't the only way to memorize concepts.

In Pre-Algebra, you will learn about and explore topics including **integers, order of operations, algebraic expressions, one and two-step equations, proportions, percents, probability, geometry, and linear equations**.

Why Is the Order of Operations Important? The PEMDAS rule **helps you from arriving at the wrong answer if you mix up the order of parentheses, exponents, multiplication and division, and addition and subtraction**.

**Show/explain the steps taken to solve a problem**. Explain their findings in a clear and organized manner. Restate the question. Answer all parts of the question.

There are three phases to conducting a workshop: **planning, preparation, and implementation** (actually doing it). In addition, once you're done, it's important to follow up with participants to get feedback on the workshop, so you can improve it the next time. We'll look at each of these phases separately.

To justify a solution, students will need to be able to **use appropriate mathematical language to give reasons for the particular approach used to solve a problem**. Any time that a student produces a 'solution' in an attempt to solve a problem, that 'solution' needs to be justified.

The order of operations is **a rule that tells the correct sequence of steps for evaluating a math expression**. We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). Created by Sal Khan.

**And finally, what about the example from the beginning?**

- Start with:7 + (6 × 5
^{2}+ 3) - Parentheses first and then Exponents:7 + (6 × 25 + 3)
- Then Multiply:7 + (150 + 3)
- Then Add:7 + (153)
- Parentheses completed: 7 + 153.
- Last operation is an Add:160.

The order of operations can be remembered by the acronym PEMDAS, which stands for: parentheses, exponents, multiplication and division from left to right, and addition and subtraction from left to right. There are no parentheses or exponents, so **start with multiplication and division from left to right.**

Many students learn the order of operations using PEMDAS (Parentheses, Exponents, Multiplication, Division…) as a memory aid. This very often leads to the misconception that multiplication comes before division and that **addition comes before subtraction**. Understanding the principle is probably the best memory aid.
