MDAS OPERATION
In mathematics,logical operation is the most important to consider. It is by its gradual order where the final answer can reliable. Constant daily practice is the most advice by many to master mathematics. By basic operation, it should be the Multiplication should be the first in the series of operation, followed by Division, Addition, and Subtraction. Majority got stuck on this because some do not understand how to handle the operation. Multiplication will be treated at first and should not be intervene by Division at the same time. After treating the Multiplication clearly then that is the time for Division. Again do not manipulate them together. The result of the two gradual operations should be then followed by Addition and Subtraction. Let's check with the given illustration.
Based on the description, Multiplication is the first to operate followed by division, addition and lastly subtraction.
Illustration.
1. 12*3/4 + 5 - 3 = 36/4 +5 -3
= 9 + 5 - 3
= 14 - 3
= 11
From the example above. 12 and 3 should be treated because they have "multiplication" as operator. And 12 of 3 is 36 (see the initial result). After multiplication was completely done, division will be the next, and that is to say 36 divided by 4 which gave us 9. The next thing to do is addition to be followed by subtraction. Hence, our final answer is 11 and that is 36/4 +5 -3 = 9 + 5 - 3 = 11.
2. 4*4 / (2*2) - 2 + 3 = 16 /4 -2 +3
= 4 -2 + 3
= (guess what is the final answer)
Our second example was intentionally made for you to finish. What is the answer to this simple math with MDAS operation? Is it 5? Some say its negative one (-1) So what is then is the final answer?
3. 5 + 4*3 - 6 / 2 * 3 = ? (try to fill out the solution,remember the MDAS rule)
The third example was leaved for you to finish. Follow the simple steps of the operation. Check where is the multiplication as operation located. So it is between 4 and 3. Followed by the division which is 6 and 2 but it is multiplied by 2. Next is the 5 added to the product of 4 and 3.
Let us try the other two problems.
4. 15/3 + (4*2)/4 - 16 / 3 * 2 + 1 =
5. 2*3 + 6-2 * 3 + 6/2 - 1 =
