Help me with this math
what is this type of problem called?? how do I solve it?? step by step,please 7.5 - (16 - 4) 2 + 8 (btw the point between the seven and five stands for multiplication)
as yes PEMDAS or Please Excuse My Dear Aunt Sally, or Parenthesis, Exponets,Multiplication,Division,Addition,Subtraction do it in that order
I wrote (16 - 4) 2 + 8 and I understand your answer but how did you get 24??
oops yeah I was wrong lol gotta read better. thnx modest
PEMDAS! (parenthesis, exponenets, mutiplacation, division, addition, subraction)
7x5 - (16 - 4) 2 + 8 7x5 - 12 x 2 + 8 35 - 24 + 8 11 + 8 = 19!
your answer is 19.
:)
the other answer is wrong because he thought there was a +sign between (16-4)and 2
is the problem (16-4)2 or (16-4)+2?
ok… you can solve it if you remember the correct order… I remember it like this Please Excuse My Dear Aunt Sally
parenthesis, exponents, multiply, divide, add subtract.
so 7x5-(16-4)2+8 7x5-(12)2+8 7x5-24+8 35-24+8 11+8 19
does this make sense?
its an equation.you will have to do order of operation to complete. first you do whats in the ( ) so your problem will look like this: 7.5 - 12 + 2 + 8 then you will have to do the multiplication so then it will be this: 35 - 12 + 2 + 8 then you just subtracrt and add left to right and you will get: 23 + 10 = 33 =]
oh wait I see how you got 24! and thanks guys for helping me
