Only people who are good in mathematics pls reply.

Question:-1+1×1-1=?

Method that I used:-1+1×1-1= 1+1-1= 2-1= 1

Method that 98% of class used:-1+1×1-1= 2×0= 0.

WHICH METHOD IS CORRECT??​

Answer 1

Answer:

method that u used is right

because the class didnt follow the rules of bodmas in their calculations and hence their ans is wrong .

Answer 2

Answer:

Your method is correct

The reason is that you used BODMAS to solve the problem but others didn't.

BODMAS stands for:

B - Bracket

O - Off

D - Division

M - Multiplication

A - Addition

S - Subtraction

This shows the order in which one should solve a mathematical problem with more than one operations ( mathematical operation of BODMAS are :- +,-,×,÷,(),off )

Also correct way of solving 1+1×1-1 is:-

1 + 1 × 1 - 1

Consider multiply sign first

Then it becomes:-

1 + 1 - 1

Now addition should be considered first

Then it becomes:-

2-1

Now all we need to do is to Subtract 1 from 2

So our final answer is 1

Hope this helps you
