Today I want to share what Is BODMAS Rule & How to use it?

BODMAS rule decides the order of operations for add, subtract, multiply, divide, etc as below shown
B-Brackets (do all operations contained in the brackets first)
O-Orders (powers and square roots etc)
D-Division
M-Multiplication
A-Addition
S- Subtraction

Let’s see an example and check how BODMASS Rule works
30-(2*6+15/3) +8*3/6

Step1: Brackets
2*6+15/3 = 12+5 = 17

Step2: Division
30-17+8*1/2

Step3: Multiplication
30-17+4

Step 4: Addition and Subtraction
30-17+4=17


20+30-5/4*2+ (1+6)
(5-6/4)+9*7
1-6*(2+9)/8


BODMAS Rule is very helpful in solving various algebra math problems.

Does it mean that if an operation $o_1$ is located above $o_2$ in this list, then $o_1$ is done before $o_2$? Then 30 - 17 + 4 should be evaluated as 30 - (17 + 4) since addition is above subtraction, so the result is 9.

I just tried that on Excel and the answer was 17.

Yes, the correct answer is 17, so the impression one can get from post 1 that the operations are done in the order they are listed is incorrect.
