Now we will study how to solve mathematic problem has many operations in it.
First, we will solve the ''Brackets'', if there is a bracket in the operation.
We will solve first the brackets.
Second, we will solve the ''Division''.
And ''Multiplication''.
After that, we will solve the ''Addition'' and the ''Subtraction''.
Then again, to solve mathematics problem has many operations in it, first.
We will solve.
The brackets, the brackets first, then after that, we will solve the division and the multiplication.
From left to right, we will solve the division and the multiplication, then we will solve the addition
and subtraction.
Then.
From up to down, do first the brackets, then division and multiplication.
At last, addition and subtraction.
This is the order of the solving of many operations,
in one problem.
Or in the same problem.
Math problem.
At first, we have this problem.
There is a division, multiplication and brackets, addition how to solve this problem.
We said before that we will start with the '' Brackets'', we will start with the operation.
In between brackets, then division and multiplication from left to the right.
Then addition and subtraction.
So in this problem, we will start by the
operation in between bracket.
The operation in between bracket is ''two plus two'', two plus two is four.
After that, we will.
Solve the operation from the left to the right.
From the left to the right, the division and multiplication.
Then, the addition and subtraction, here we have division and multiplication, so we will solve ''eight divided two''
first.
''Eight divided two'' is four.
Then multiplied ''four by four''.
Which is 16.
Finally, the result of this operation.
Is very, very easy, it will be 16, we
have just.
Follow.
This.
Conditions, we will solve the brackets first then,
division and multiplication from the left to the right.
then addition and subtraction from the left to the right.
Solve the following.
Five minus two in between brackets.
Plus, nine.
Multiplied by one minus four divided by two.
Equal unknown..
First, we will start.
by the operation in between brackets.
''Five minus two'' is three.
Then bring down the other
numbers and signs, plus nine multiply one minus four divided two equal unknown.
Second step, we will do the division and the multiplication operation from left to right.
Here we have nine
by one'' sorry'' , and four divided by two, we will start by ''nine multiply one'' nine multiply
one is nine minus four divided two.
Then ''four divided two''.
Three plus nine minus ''four divided two'' is two.
The third step, addition and subtraction from left to the right, we have three plus nine then minus
two, we will start by ''three plus nine'' ,''three plus nine'' is,
twelve.
''Twelve minus two'' is ten.
This is the result of this operation, ten is the result of this operation.
Again, we will revise what we.
Learn.
We will start by the brackets.
In the operation or is the problem that consists of many operations.
We will start by the brackets first, then division and multiplication.
Finally, addition and subtraction.
Solve the following.
Eight plus fourteen divided by seven multiplied by three minus five.
We said before that we will start by brackets ,if there is no brackets,
we.
start
solving this problem from left to right by division and multiplication, then addition and subtraction.
We will start by division and multiplication, first from the left to the right.
Fourteen divided seven, then seven multiply three.
''Fourteen divided seven'' bring down eight plus ''fourteen divided.
seven is two.
Then multiply three minus five.
The second step, we will multiply ''two by three''.
Bring down eight plus ''two by three'' is six minus five.
Then the third step.
Addition and subtraction from the left to the right, eight plus six comes first which is fourteen minus
five
Finally, ''fourteen minus five'' is nine.
