Top 10 Bodmas Questions

Understanding BODMAS: A Step-by-Step Guide

Source: topperlearning.com

Ever feel lost in a math problem, not sure where to start? BODMAS can help. It's like a special map, telling you the right path through tricky math.

What is BODMAS?

BODMAS is a way to remember the order of steps in math problems.

• Brackets (parentheses) – First
• Orders (powers and roots) – Second
• Division and Multiplication – Third, whichever comes first from left to right.
• Addition and Subtraction – Last, whichever comes first from left to right.

Easy, right?

Why is BODMAS Important?

Math needs rules! Imagine a game with no rules, chaos would follow.

The rule of BODMAS gives a standard way of working out problems. This stops us from getting wrong answers. With the same math, it shows different people get the right answer. Everyone following the same rule helps with a clear result!

How to Apply BODMAS to Simple Expressions

See a problem? Follow the BODMAS rules.

Let's say: 5 + (2 x 3) – 4.

1. Brackets first: (2 x 3) = 6. So we now have 5 + 6 – 4.
2. No more brackets. Division or multiplication come next, no in this problem. So now we have 5 + 6 – 4.
3. Addition/Subtraction (from left to right): 5 + 6 = 11. So now we have 11 – 4.
4. 11 – 4 = 7. That's the answer.

BODMAS with Powers and Roots

Roots and powers are like special multiplication. For example:

2³ x 5 – 10 ÷ 2

1. Powers first: 2³ = 8.
2. Next: Multiplication/Division, left-to-right : 8 x 5 = 40 10 ÷ 2 = 5
3. Now: 40 – 5 = 35. Answer: 35

BODMAS with Brackets and Parentheses

Sometimes brackets show up inside of other brackets!

Example: ** (10 + 5)² – 5 x 2**

1. Work inside the first set of brackets, first: 10+5 = 15 . The problem now looks like (15)² – 5 x 2
2. Next step: 15² (powers). 15 times 15 = 225.
3. Next is multiplication. 5 x 2 = 10 Now we have 225 – 10.
4. Finish the addition/subtraction (in order): 225 – 10 = 215. Your answer!

Common BODMAS Mistakes

Be careful of tricky spots! The common mistake is to miss the left to right part.

People often miss the left-to-right step in multiplication or division. The rules apply, whichever of those two is encountered in order from left to right

Following BODMAS is a useful tool, one that'll take you through hard problems. Now go out there and solve some maths using this rule!

Top 10 Tricky BODMAS Questions to Test Your Skills

Ready to put your BODMAS knowledge to the test? These tricky questions will check how well you understand the order of operations.

Question 1: Simple Arithmetic with BODMAS

Let's start with a simple one: 5 + (2 x 3) – 4

• First, calculate inside the brackets: 2 x 3 = 6. The problem changes to 5 + 6 – 4.
• Next step is addition or subtraction (left to right) : 5 + 6 = 11. So we have 11 – 4 = 7

Question 2: BODMAS with Exponents

Here's a question with a power: 2³ x 5 – 10 ÷ 2.

• First step: find 2 to the power 3 (or 2 raised to the power 3). 2³ = 8. Our problem now is 8 x 5 – 10 ÷ 2.
• Next step is multiplication or division. We solve these operations from left to right order. 8 x 5 = 40. 10 ÷ 2 = 5. Our problem is now 40 – 5.
• Finally: 40 – 5 = 35

Question 3: Evaluating Expressions with Brackets and Multiplication

A problem with brackets and multiplication. Example 10 + 2 * (7-5)

• First step, calculate inside the bracket: 7-5 = 2. This makes it: 10 + 2 * 2
• Now do the multiplication 2 * 2= 4. We have 10 + 4
• Finish with addition. 10+ 4 = 14.

Question 4: BODMAS with Nested Brackets

A step harder: 5 – 2 * (6 + 4 – 8)/ 2.

• Focus on inner brackets, first, following BODMAS (in this case). 6 + 4 = 10 , 10 – 8 = 2 . The new problem: 5 – 2* 2/ 2.
• Next step involves doing multiplication/division first: 2 * 2 = 4 and 4 /2 = 2. New problem : 5 – 2
• Addition/ subtraction : 5 -2=3

Question 5: Complex BODMAS Problem with Multiple Operations

12 – 3 x 4 + 5(6 – 2)

• Tackle the brackets first: 6 – 2 = 4. The new problem is now 12 – 3 * 4 + 5 * 4
• Then, handle multiplication: 3 * 4= 12 , 5 * 4= 20. We now have 12 – 12 +20.
• Lastly, work through addition and subtraction (in order) 12 – 12 + 20 = 20

Question 6: Combining BODMAS with Negative Numbers

This question has negatives too: 2(3 + 5) – 1(4 – 6).

• Solve bracket : 3 + 5 = 8 and 4 – 6 =-2. Problem now 2(8) – 1(-2)
• Do multiplication first (following BODMAS). 28= 16 , 1-2 = -2. New problem: 16 – (-2)
• And finish it, solving addition/subtraction: 16 – (-2) = 18

Question 7: Nested Brackets and Division

** (6 ÷ 2)(3 + 2) + 4**

• Solving inner bracket: 3+2=5. Our new problem : (6 ÷ 2)(5) + 4.
• Multiplication/division : 6÷2= 3. Then multiply 3*5 = 15. Now problem is 15 + 4.
• Addition : 15 + 4= 19

These were some tricky questions; remember the order to tackle them successfully. Mastering BODMAS will lead to the accurate solutions every single time, no matter how tricky the equation might look!

7 Common Mistakes to Avoid When Using BODMAS

Source: co.uk

Following BODMAS is important, but making mistakes is normal. Let's learn common errors to avoid them.

1. Incorrect Order of Operations

The most common problem. People forget the correct steps!

• Sometimes, people do addition before multiplication or brackets. The right order matters!
• The rules dictate steps in a specific order: brackets, powers, multiplication/division, then addition/subtraction

2. Misinterpreting Brackets

Brackets (parentheses) are vital, showing what to solve first.

• Sometimes, the wrong bracket part gets overlooked or misunderstood. Be extra careful
• People sometimes forget to calculate inside the bracket first and start working outside brackets without solving things within brackets properly, which leads to calculation mistakes.

3. Confusion with Division and Multiplication

These are done in order, whichever comes first.

• People sometimes get confused about which one to do first! Remember to go in order. Whichever comes first!
• Both division and multiplication should be carried out first, following left to right rule! Then comes the addition/subtraction

4. Overlooking the Left-to-Right Rule

Multiplication/Division or addition/subtraction have a particular order (left to right)

• Sometimes, people skip the part to work in the exact left-to-right order of calculations after solving the priority parts like brackets. That leads to some wrong outcomes!
• For both division/multiplication or addition/subtraction, we need to work from left to right in calculations if those steps appear multiple times within a particular calculation sequence. The BODMAS rules are well-explained in a strict format.

5. Mishandling Negative Numbers

Negatives can cause confusion in calculations.

• People often mess up negative signs. Double check for these signs to avoid miscalculations
• Negative signs combined with other operations, including powers and roots in complex calculations need careful handling. Mismanagement of the negative numbers can alter the whole result significantly

6. Errors with Exponents/Orders

Powers/roots can trip people up.

• Sometimes, people miscalculate the powers. Always be sure the exponent (top number) part is handled properly to get the right result.
• It's easy to mistake the value or how roots operate

7. Ignoring Implicit Multiplication

Hidden multiplication signs cause confusion.

• Sometimes there aren't explicit (obvious) signs. They mean 'times.' Watch out!

Understanding and avoiding these seven common errors will improve math problem-solving and enhance one’s grip and grasp over BODMAS. Always make a conscious and mindful effort to calculate each and every step correctly, ensuring the results to match the rule. This careful practice is important.

5 Real-World Applications of BODMAS

BODMAS isn't just for schoolwork. It's a vital tool in many everyday situations.

1. Calculating Finances
