Why was pemdas created?
Pemdas was created, because it is the order in which you can solve problems. (order of operation) Parenthesis Exponents Multiplication Division Addition Subtraction If we didn't have Pemdas everything would be all mixed up, and the answer would be wrong. Pemdas is the rules of order in which how to solve a problem.
In mr Fred's class the students are learning about the order of operations. Jefferson is frequently forgetting pemdas but George can remember it without the help of pemdas. How many Fs?
It is not clear how many times Jefferson forgets PEMDAS based on the given information. Additionally, the number of times George remembers PEMDAS without the help of PEMDAS is not stated. Therefore, it is not possible to determine the exact number of times Jefferson forgets PEMDAS or how many times George remembers it.
How can the properties of operations be used to solve problems involving integers and rational numbers?
I think that this has to do with PEMDAS. It can also stahnd for, Please Excuse My Dear Aunt Sally. When answering a question like this it always makes me think of the strategy PEMDAS. It is a strategy that can be used for problems like, for example: 2+(9×10)/21.
What is 8 minus 5 plus 4 using PEMDAS?
Using pemdas, the subtraction and addition happen at the same time. If there are no parenthesis, then you just go from right to left. 8-5=3 3+4=7 So 7 is your answer.
What is 15-5 plus 9 - 2 in PEMDAS order?
Pemdas says that addition and subtraction can be done in any order, so it doesn't matter. 15 - 5 = 10 10 + 9 = 19 19 - 2 = 17 The answer is 17. Pemdas- Parentheses, Exponents, Multiplication/Division, and Addition/subtraction. The slashes mean that those two can be done in any order, and you will get the same answer/
