## Is Pemdas or Bedmas correct?

In the United States, the acronym **PEMDAS** is common. It stands for Parentheses, Exponents, Multiplication/Division, Addition/Subtraction. Canada and New Zealand use **BEDMAS**, standing for Brackets, Exponents, Division/Multiplication, Addition/Subtraction.

## Did they change Pemdas?

In some areas of the world **they** use a different acronym (such as BODMAS or BEDMAS), but these are still the same thing as **PEMDAS** (Please Excuse My Dear Aunt Sally). Believe it or not, the **PEMDAS order of operations** is not only still correct, but it’s always been what you just described.

## Does the order of Pemdas matter?

Yes, **PEMDAS** means parentheses, exponents, multiplication, division, addition, and subtraction. Multiplication and division go together, so you **do** whichever one comes first.

## What can I use instead of Pemdas?

GEMS stands for “Groupings, Exponents, Multiply/Divide, Subtract/Add”. Why **do** we like it better? The G stands for groupings so it includes parentheses, brackets, braces, and fraction bars. The E stands for exponents just like in the old **PEMDAS** acronym.

## Is Pemdas always the rule?

Simple, right? We use an “**order of operations**” **rule** we memorized in childhood: “Please excuse my dear Aunt Sally,” or **PEMDAS**, which stands for Parentheses Exponents Multiplication Division Addition Subtraction. * This handy acronym should settle any debate—except it doesn’t, because it’s not a **rule** at all.

## Is it 16 or 1?

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.

## Why does the order of operations exist?

The **order of operations** is a rule that tells you the right **order** in which to solve different parts of a math problem. Subtraction, multiplication, and division are all examples of **operations**.) The **order of operations** is important because it guarantees that people can all read and solve a problem in the same way.

## What does the G in gems stand for?

**G.E.M.S.** is a great strategy for students to use to learn the Order of Operations. It **stands for**: **G** – Grouping Symbols (parentheses, brackets, braces) -> ( ) [ ] { } E – Exponents (the exponent tells how many times the base is multiplied by itself) M – Multiply/Divide

## Does Pemdas apply when there are no parentheses?

**Without parentheses**, **PEMDAS** rules imply that you must **do** division first. With **parentheses**, the 3x now becomes a group.

## Does multiplication always come first?

Order of operations tells you to perform **multiplication** and division **first**, working from left to right, before doing addition and subtraction. Continue to perform **multiplication** and division from left to right. Next, add and subtract from left to right. **Multiply first**.

## Do calculators use Pemdas?

This rule is so widely known that an acronym — **PEMDAS** — is often **used** to describe this. Windows **calculator** is just a basic **calculator** but you can change it so you can include your parentheses.

## Why is Pemdas in that order?

The **order of operations** was settled upon in **order** to prevent miscommunication, but **PEMDAS** can generate its own confusion; some students sometimes tend to apply the hierarchy as though all the operations in a problem are on the same “level” (simply going from left to right), but often those operations are not “equal”.

## What does the A stand for in Pemdas?

**PEMDAS** is an acronym for the words parenthesis, exponents, multiplication, division, addition, subtraction. Given two or more operations in a single expression, the order of the letters in **PEMDAS** tells you what to calculate first, second, third and so on, until the calculation is complete.

- 3 – Have students practice with a cooperative activity.
- 4 – Let students work on a puzzle.
- 5 – Have students complete an individual activity.
- 6 – Decorate your room with the
**order of operations**. - 7 – Show students a video.

## How do you teach Pemdas?

If your students have already studied exponents, you can **teach** the acronym **PEMDAS** which stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. The phrase “Please Excuse My Dear Aunt Sally” will help them remember the order of those letters.
