Question
Simplify
[tex]2(12 - \frac{18}{3} + 4)[/tex]
Answer:-
ATQ->
[tex]2(12 - ( \frac{ \cancel{18}^{ \: \: \: 6} }{3} ) + 4 \\ 2(12 - 6 + 4) \\ 2(16 - 6) \\ 2(10) \\ 20 \: \: is \: your \: ans[/tex]
Answer:
Depends on how the 3 and the 18 are positioned in the fractions on the equation.
47/3
4
Step-by-step explanation:
Step 1. To simplify this, you need to know one of the most basic sayings in math which summarizes the Order of Operations: PEMDAS
Using PEMDAS:
P- Parenthesis
E- Exponents
M- Multiply
D- Divide
A- Add
S- Subtract
P- Parenthesis: We start off by preforming the parts of the equation within the parenthesis.
The 2 on the outside of the parenthesis, will not affect anything until we deal with what is inside the parenthesis.
The next part that we do, is to go through the rest of the steps, looking for either exponents, multiplication or division, skipping over the adding and subtracting until those are done.
The next part that we see, is Division.
D- Division
We find the point of division after the 18. The value we get has to be either:
a. 3/18
b. 18/3
depending on what you were asking for.
The equation, 2(12-18\3+4) at the bolded point, states that the division should be 1/6 because of the way of the division symbol.
Now the equation should either be one of the following:
a. 2(12-1/6+4)
b. 2(12-6+4)
A-Addition
Now, we can add the 4 to the number we got before, which should get us either
A. 1/6+4
B. 6+4
which added together gets us either
A. 25/6<=>4+1/6
B. 10
S-Subtraction
Now, we subtract both parts from the value of 12 getting us:
A. 12-(4+1/6)=12-4-1/6=8-1/6=7+5/6<=>47/6
B. 12-10=2
M-multiply:
Now we move on to the 2 we put aside earlier and multiply both of the answers:
A. 2(47/6)=47/3 or 15+2/3
B. 2(2)=4
Thus the answer is either 47/3 or 4
