What does 53 mean Nickolas?       Do you know?      

 

By the way,   53  can also be written as  5^3

Anyway, this is an order of operation question.

 

You are probably taught the order as PEDMAS

 

1) Parenthesis,

2) Exponents (the little 3 in your question is an exponent)

3) Division and Multiplcation are euqally important - you do them from left to right.

4) Addition and Subtraction are also equal important - do them from left to right

 

\(5^3\div(13-8)\times 2\)

 

Do it one step at a time in this order :

 

Parentheses

Exponent

Division    

Multiplication

Pemdas is the formula you need to work with.

 

Parenthesis

Exponents

Multiply

Divide

Add

Subtract

 

5^3 ÷ (13 - 8) × 2

So figure out parenthasis first 13- 8 equals 5

5^3 ÷ 5 × 2 

Then figure the 5^3 = 125

125 ÷ 5 × 2 

Find 125 ÷ 5 = 25

25 × 2

50

 

I hope this helps ;P

Am i the only one that noticed that on the top of the picture there is the tabs and the one he is currently in is an exam? That seems a little fishy. Is Little nick using this site to cheat on an exam?

Thanks IamJeff

Cheating is a constant concern and a big problem on this forum.

For this reason it may be better to make people wait before they get an answer.

 

Plus

There is often no need to give the final answer.

What i had written was more than adequate. 

    EmeraldWonder was trying to be helpful but she did not add anything of value.  (Except cheat value)

   (She also gave an incorrect impressions - Multiplication is NOT done before divide, they are equally important)

 

If this is a test it should be timed shouldn't it?  Or even put up and taken down at set times?

So if our answers were delayed for an hour it should not be a problem???

I am nor very familiar with internet testing.

 

I expect past papers, which are just homework, might sometimes be presented like this??

It is concernng though.

I wasn't meaning to be mean Emerald. 

I am not good at wording things tactfully.

 

I really do like that you are active on the forum and I am sorry that we have got off on the wrong foot. :)

Maybe we can start over?
