#3 explained.. The confusion here stems from a misunderstanding of the BODMAS (or PEMDAS) rule, particularly how it applies to addition and subtraction. ### BODMAS Rule Explained: - **BODMAS** stands for **Brackets, Orders (i.e., powers and square roots, etc.), Division and Multiplication (from left to right), Addition and Subtraction (from left to right)**. - According to this rule, multiplication and division are performed before addition and subtraction. However, addition and subtraction are of equal precedence. This means when both operations appear, they are performed from **left to right**. ### The Expression: 50 - 40 + 10 Let's evaluate the expression step by step: 1. **First Operation (Left to Right)**: - Start with subtraction: \( 50 - 40 = 10 \). 2. **Second Operation**: - Then, add 10: \( 10 + 10 = 20 \). ### Why 20 is the Correct Answer: - In the expression `50 - 40 + 10`, you perform the subtraction first, followed by the addition. According to the BODMAS rule, addition and subtraction are done **left to right** when they appear together without parentheses. - **Important Note**: The BODMAS rule does not mean addition is always done before subtraction; rather, it means that addition and subtraction are done in the order they appear from left to right. ### Conclusion: The correct way to evaluate `50 - 40 + 10` is to first subtract 40 from 50 (giving 10), and then add 10 to that result, which gives 20. The answer should indeed be 20, not 0. Hope it will help you all :)
@riva saha5483 , hey bro you can add the positive number then subtract from negative number get Eg- : 50-40+10 , 50+10 = 60 further subtract because 40 is a negative number 60-40= 20 it's so simple why are doing complex My suggestion is add all positive numbers then subtract from get all positive number

According to the BODMAS/BIDMAS rule we perform operations in a specific order. However, when it comes to addition and subtraction, they are performed from left to right, as they appear in the expression.
Thankyou sir for giving this wonderful session (back to basics). Aapne sahi me depth tak btaya aur jo mujhe pta nhi tha vo aj pta chala maths me thankyou sir .... I always pray for your mother's good health, she will be get well soon ❤❤❤❤

You are just amazing sir.. aap ki wajah se maths achha lagne laga hai... Warna maths me 10 number bhi nahi aate the
Sir mne Aaj tk aisi class nhi dekhi simplification ki apne bhut acche se basics clear kr diye m soch bi nhi skti ki aise koi pda skta h sir Thank you so much🙏🙏🙏 Your dedication 🔥🔥🔥 Amazing class❤ Sir you are really great and you have very deep knowledge 😊🙏🙏🙏🙏🙏🙏🙏
Sir, what will be the approx value of 4.2X1.2, according your method it will be 4X1=4 but in actual it will be 4.2X1.2=5.04 approx value will be 5... So which one is correct
Salute h sir aapki hard work or aapka dedication ko Dil se salam h sirr...isko words me ni kh skte ye feel hota haii.....nd sir aap black me ache lgte hai
Thank you, sir🙏. Maths has never felt this easy. I literally had a math phobia until I watched this video; my concepts are much clearer now. After understanding the #21 core concepts that you taught in this video, I'm able to solve all the problems easily.
Sir doubt 🙋♂️ According to bodmas to aapne bataya ki kaise solved krne hai questions but jo (#3) no. Que 50-40+10 hai to answer 0 aana cahiye na sir Kuki 50 - 50 = 0 yaha pe samajh nahi aaya please thoda cleare karwa dijiye
