Hi, everyone, and let's complete our previous lecture about SEAL writing and writing operations and
writing formula, and you must know the sequence of operations here.
You will find the order of order of operation executing.
So you will find that multiplication, precede division and division, precede additions and additions,
precede subtraction and subtraction precede logical operations.
So let's take this example.
If you want to follow the stay of execution, the following formula to multiplication, five plus three.
The question is which operation will be executed first?
Multiplication or addition, let's get back to the operation sequence and we will see that multiplication,
a multiplication, precedes addition.
So the first thing will be executed here is to multiply it by five and the result will be.
After that, you will add three.
So the final result will be 30.
In the next example here, do multiplication two, parentheses five plus three, which operation will
be executed?
First
parentheses makes priority for addition.
So the first operation here is additional five plus three.
The result is eight and eight multiplied by two.
So the final result will be 16.
In the next example, you have two parentheses division.
Three Operation Multiplication addition.
And the vision and addition, so first brought to bear on Athersys, the first operation will be five
plus three.
The result is eight.
Multiplied by two.
So the result is 16
divided by two, so the result will be eight added to do so, the result will be 10.
The last example here, you have addition, you have multiplication, division and two parentheses.
So Burroughs's makes priority for its operation.
So the first operation executed here will be five plus three and the result will be eight multiplied
by two.
Multiplied by two, so the result will be 16 and parenthesis makes priority two additions over division.
So two plus two is four.
After that, we can apply the vision.
So 16 divided by four, the result, the final result will be four.
OK, OK.
So what is the result of this equation let's.
Take example and learn how to write this equation using Microsoft Excel.
Let's practice and write this formula plus two.
Division five.
Plus three, the result will be 13.
Next example here to multiply Orbin to parentheses.
Five plus three, and the result will be 16, the third example here to multiply two, parentheses five.
Plus three.
Divided.
But two plus.
Do so here, Division Brisset addition.
So the first operation will be five plus three is eight, eight by two is 16, 16, divided by two is
eight plus two then.
So the final result will be 10.
OK, that's right.
Also.
Two multiplied by two parentheses five plus three divided by two, parentheses two plus two, so here
parentheses makes priority to additions.
So the first thing will be executed here is five plus three.
The result will be eight eight multiplied by two.
The result will be 16.
And Bernath says, makes it a priority to addition then division.
So here two plus two is four, so 16 divided by four.
The final result will be four.
And that for that.
Right.
OK, if you don't understand anything, please let me know and we will discuss it with more detail.
OK, so.
Let's try to solve this equation, what is the result of this formula?
Let's write it.
Let's practice to write it equal, to multiply the parentheses.
Five.
Minus three.
Forward slash.
Two parentheses.
Two plus two.
Bower do minus one.
So what is the result of this equation, presenter?
The result will be minus O point seven five.
The question is, what are the steps executed to give this result?
What is the sequence of operations?
OK, let's track the execution of this equation step by step.
So parentheses gives priority to substraction operation.
So five minus three is the first thing multiplied by two.
So the result will be for this about the first term on the left hand side.
After that parenthesis gives priority to two plus two, the result will be four and four will be powered
by two.
So the result will be 16.
After that division has priority, then subtraction.
So four will be divided by 16 and the result will be O point to five.
After that we will subtract oh point to five from the one and the result will be minus O point seven
five.
That's right.
This execution is right.
Thank you and see you in the next lecture.
