Answer 1

@leenathan If you're not busy can yew help me??

Answer 2

im in a meeting

Answer 3

use pemdas

Answer 4

ok

Answer 5

Do you know the correct order of operations?

Answer 6

Do you know what PEMDAS means and how to use t?

Answer 7

Yes

P- Parenthesis
E- Exponents
M- Multiplication
D- Division
A- Addition
S- Subtraction

Answer 8

Yes, you got the letters correct, but the order is this:

First: P - Parenthesis
Second: E - Exponents
Third: MD - Multiplication and Division in the order they appear from left to right
Fourth AD - Addition and Subtraction in the order they appear from left to right

Answer 9

In this problem there is an exponent, since E is first, do the exponent first.
The way to solve a problem like this without forgetting any operation is to write the entire problem down.
Then do one step at a time in the correct order following PEMDAS and copy everything else down.
Do one step per line, but copy everything else, so you don't forget part of the problem.

Answer 10

\(\Large10^2 \div 25 \cdot 20 + 4 \div 2 - 14\)

Answer 11

Oh Ok

Answer 12

\(\Large \color{red}{10^2} \div 25 \cdot 20 + 4 \div 2 - 14 =\)

\(\Large =\color{red}{100} \div 25 \cdot 20 + 4 \div 2 - 14 \)

There are no parentheses or exponents now.
What do you do next?

Answer 13

AD??

Answer 14

Addition and Division...................?

Answer 15

or Subtraction

Answer 16

Where did you see AD above where I explained PEMDAS?
I only see
P
E
MD
AS

Where is AD?

Answer 17

Sorry. I did make a mistake above.
The last step is AS, not AD.
Let me write it again:

First: P - Parenthesis
Second: E - Exponents
Third: MD - Multiplication and Division in the order they appear from left to right
Fourth AS - Addition and Subtraction in the order they appear from left to right

Answer 18

We had no parentheses.
We had an exponent and we did it.
Now we have MD.

Answer 19

\(\Large =\color{red}{100 \div 25 \cdot 20} + 4 \div 2 - 14\)

Look above.
There is a division and a multiplication.
They are both part of MD, so we do them in order from left to right.
What is 100/25 = ?
