The order in which you carry out the procedures outlined by PEMDAS, BODMAS, and DMAS is crucial.
Mathematical method order is a common source of stress for GRE takers. The acronym goes under several other names, including BODMAS, DMAS, and PEMDAS.

Here are a few frequently used mathematical expressions:
In mathematics, a plus symbol (+) indicates an addition to the sum or number.
The symbol represents a difference or subtraction.
The or sign might be multiplication or product.
The dividing symbol might be either / or.
The brackets and parentheses used in programming are the [] and [] symbols ().
Absolute value bars are not brackets or parentheses. They must be evaluated using additional criteria as they are not interchangeable symbols. In the next section, we’ll talk about absolute value bars. An example of Multiplication is 66 * 3. The four fundamental arithmetic operations of addition, subtraction, multiplication, and division are all considered mathematical “operations.”
But if you do come across anything that’s comparable to…
7 × 9 + (2 × 52 – 3 ÷ 6 × 14)
Can you please tell me what fraction of the entire you should figure out first.
Therefore, humans decided, aeons ago, to adhere to the following rules while doing calculations:
Step one: complete the information in brackets.
4 × (5 + 3) = 4 × 8 = 32 (right) (right)
4 × (5 + 3) = 20 + 3 = 23 (wrong) (wrong)
Before multiplying, dividing, adding, or subtracting, apply exponents, powers, or roots.
5 × 22 = 5 × 4 = 20 (right) (right)
5 × 22 = 102 = 100 False, False (wrong)
Integers must be multiplied or divided before they may be added or subtracted.
2 + 5 × 3 = 2 + 15 = 17 (right) (right)
2 + 5 × 3 = 7 × 3 = 21 (wrong) (wrong)
Just how on earth am I meant to keep…? PEMDAS!
Two parenthesis are placed before the body of the text.
E-Bracket exponents
MD
Discussed are addition and subtraction (they both have the same rank and if they come together, then solve from left to right)
30 ÷ 5 × 3 = 6 × 3 = 18 (right) (right)
30 ÷ 5 × 3 = 30 ÷ 15 = 2 (wrong) (wrong)
Addition and Subtraction according to the AS Mathematical Standard
In the UK, this method is termed BODMAS (Brackets, Orders, Divide, Multiply, Add, and Subtract) and in Canada, BEDMAS (Brackets, Exponents, Divide, Multiply, Add, Subtract). Shortened to its three-letter abbreviation, DMAS (Divide, Multiply, Add, Subtract). Basically, everything comes down to the same thing.
Don’t be confused by the fact that division follows multiplication in this notation; both operations are treated with the same weight. According to PEMDAS, one must first master multiplication and division before moving on to addition and subtraction.
Considerable Examples
The total of 35, 5, and 2, 6 is equal to 66 because these three groups of numbers are directly related to one another.
(35 ÷ 5) + (2 × 6) = 19
detach from
35 ÷ (5 + 2) × 6 = 35 ÷ 7 × 6
Multiplication and division are only two examples of operations that have the same “rank,” meaning that you may handle them identically by simply proceeding left to right. Several Instances
35 ÷ 7 × 6
is not
35 ÷ (7 × 6) = 35 ÷ 42,
Therefore, rather than
(35 ÷ 7) × 6 = 5 × 6 = 30,
Since we read clockwise across the world, the division symbol always comes first.
Let’s go through everything we’ve already spoken about:
35 ÷ 7 × 6 = 30
Based on the issue’s inherent structure, we solved it by moving from left to right. To get 5, we needed to divide 35 by 7. Then, we got to the sum of 30 by multiplying 5 by 6.
