MDAS Rule

What is MDAS Rule?

MDAS Rule is actually a rule to follow when we are going to solve a series of operations, that is the four  fundamental operations of real numbers. MDAS rule stands for MULTIPLICATION, DIVISION, ADDITION  and SUBTRACTION.

How are we going to use this rule?

First we have to perform all multiplications and divisions before performing the additions and subtraction.
In performing all multiplications and divisions, we should solve or read it from left to right. Do not try to solve any multiplication or division since it is easier or convenient to you to solve. Always solve from left to right whatever that comes first.
Follow the same process for additions and subtraction though we can apply the rule of signed numbers or we can also use the commutative law of addition.

Example:

1) 10 x 5 / 25 + 8 - 2 x 2 + 4 - 3
       In solving this we perform first 10 x 5 together with 2 x 2. Giving us;
           50/25 + 8 - 4 + 4 - 3
       Then we have to solve 50/25 before performing the addition and subtraction. So we have,
           2 + 8 - 4 + 4 - 3 which is equal to
          10 - 4 + 4 - 3. And the final answer is
           7.

Try these:


1)  15 + 35/5 x 8 + 12 - 7 x 4 / 2 - 6
2)  105 / 3 - 35 x 2 + 35 - 70/2 + 35
3)  50 x 3 + 50/2 - 25 + 25/5 x 10

    1. I thougth after multiplication and division, it is ADDITION first then SUBTRACTION? Then it should have been:

      10x5/25+8-2x2+4-3(multiply)=
      50/25+8-4+4-3(divide)=
      2+8-4+4-3(add)=
      10-8-3(subtract)=
      -1

    5. MDAS as I've understood it today: in solving such problem, MDAS indeed applies yet...

      when it comes to addition and subtraction, addition is not really necessary should be conducted first then. Instead, if the signs left were minus and plus, simplify the factors into its sequence from left to right.

    5. its true, that using MDAS multiplication should comes first before division. but that is not always the case. if multiplication and division are adjacent operations, the operation must be performed from left to right. meaning, the operation which comes first must be performed. same as addition and subtraction.

    NOTE: if we are going to follow the MDAS rule, the answer is -1.

    MDAS: you should always consider the signs used in the equation. and remember the rules in performing the operations with LIKE SIGNS (i.e: +positive, +positive or -negative, -negative) - the answer is always +positive... with UNLIKE SIGNS (i.e: +positive, negative or vice versa) - the answer should always be in a negative sign.

    =(10x5)/25+8- (2x2) +4-3 (here, do the MULTIPLICATION first, then proceed to the next step
    =50/25+8-4+4-3 -DIVISION
    =2+8-4+4-3 -ADDITION
    =(2+8)- (4+4) -3 -Group together those with the same signs using a parenthesis and take note of the sign outside. then the last step -SUBTRACTION
    =10-(8)-3 (thus, it becomes)
    =10-8(unlike sign)-3
    =2-3 (in determining what sign to be used, remember the rules in adding unlike signs. you should always use the sign of the larger number in determining the sign to be used in your final answer.

    1. 10x5/25+8-2x2+4-3
      i may group it by parenthesis

      [10x5]/25 + [8] - [2x2] + [4] - [3]
      50/25 + [8] - [ 4 ] + [4] - [3]

      bear in mind that inside the parenthesis are positive digits
      [4] or [+4] // [3] or [+3], if outside the parenthesis is negative sign, the entire sign inside the parenthesis will change as well.
      so it goes like this :

      [50/25] + [8] - [+4 ] + [+4] - [+3]
      2 +8 -4 +4 -3
      = 7

  23. I think the answer is correct, meaning there is nothing wrong with the computations. MDAS is correctly applied.

    What i remember (hopefully i'm not wrong)

    MDAS is divided into 2 parts: MD and AS

    MD clusters should be computed first before AS clusters

    In MD, it doesn't mean you need to compute "M" before "D".
    eg.: 4 x 3/3 =4 can be also written as
    3/3 x 4=4 or sometimes written as
    4/1 x 3/3 =4 whatever comes first the answer
    is still the same

    It is also the same with AS.
    eg. : 5-4+3-2+1 = 3 or
    -4+5-2+3+1 =3 or
    1-4+5+3-2 = 3
    *why +5 and not -5? we should always remember
    that a number is always positive(+) unless indicated negative(-)

    Note: Do not be confused with those with Parenthesis/brackets/braces as it talks about different order of computing.
    Puting Parenthesis/brackets/braces is used to modify the order of the computation following Inner to outer manner of computations

    TumugonBurahin
  47. 7 is right. Multiplication or Division ang mauna depende kung alin ung nauna sa equation tsaka na ang Addition or Subtraction... kung nuna ang division kesa sa multiplication, un ang unahin.... same with addition and subtraction... ok lang na mauna ung subtraction sa addition kung mas nauna sa equation ung subtraction.
