Do things in Brackets initially.

Otherwise, go from left to right.

**Conditions and Rules PEMDAS / BODMAS**

These conditions and rules for the general simplification of expression below:

Condition |
Rule |

a+ (b + c) ⇒ a + b + c |
Open the bracket and sum the terms. |

a– (b + c) ⇒ a–b–c |
Open the bracket and multiply the negative sign with every term inside them. (All Positive terms are negative and vice-versa) |

a (b + c) ⇒ ab + ac |
Multiply the outside term with every term within the bracket |

An additional complicated PEMDAS example

300 - (4 x 2² + 12)

We have to look at the parentheses 1st, remember. Three arithmetic operators within these brackets that tend to use PEMDAS to work out that we would like to tackle the exponent 1st.

300 - (4 x 4 + 12)

Still performing on the parentheses, there is a multiplication that ranks next.

300 - (16 + 12)

Let us end the parentheses.

300 - 28

And the final operation is that the minus.

300 - (4 x 2² + 12) = 272

**How Did You Do? **

Hopefully, you managed to induce all the answers right. If not, return and review wherever you went wrong, and skim over the principles another time.

The more you practice, the simpler PEMDAS / BODMAS becomes, and eventually, it will not even get to consider it.

As of recently, riddles like this,

appeared where one overlooks that the number of fries has modified. Or this:

These kinds of puzzles have managed to become viral, not due to the PEMDAS factor as a result of individuals who do not scrutinize the variations (Three rather than four bananas, 2 o’clock instead of 3 o’clock). Nearly everyone gets it wrong initially. However, there is additionally the PEMDAS challenge. Some get 88. except for obtaining 88, one would get to write parenthesis (2+3+3) *11.

Try these calculations:

- 3 + 20 × 3 =?
- 25 - 5 ÷ (3 + 2) =?
- 10 + 6 × (1 + 10) =?
- 5 (3 + 2) + 52 =?
- (100 + 211) - 550 ÷ 52 + 10 =?

## **Synopsis**

I hope this text has helped you to urge you to grips with what BODMAS, BIDMAS, and PEMDAS area unit. For additional in-depth scrutiny of the Order of Operations, at the side of some attention-grabbing examples, you may adore it. However, do not expect to flee while not a headache.

TIP: Work it out piecemeal and do not attempt to take shortcuts.

**Frequenly Asked Questions (FAQs)**

**1. What is the rule for BODMAS?**

The BODMAS rule gives us the correct sequence for solving a mathematical expression.

In BODMAS rule, operations are performed in parentheses first.

Next, operations are performed on exponents or powers.

This is followed by the operations on multiplication or division from left to right, whichever comes first.

Finally, the operations on addition or subtraction are performed from left to right, whichever comes first.

**2. Do you multiply or divide first in BODMAS?**

In BODMAS rule, we solve operations on multiplication and division from left to right.

We perform the operation that comes first.

**3. When do we apply the BODMAS rule?**

BODMAS Rule is applied for solving difficult mathematical expression involving more than one operation like addition, subtraction, multiplication or division.
