Question

What should Mat and Karen done to get the correct answer? Matt 6 – 4(3 – 5)2 + 30 ÷ 5 6 – 4(–2)2 + 30 ÷ 5 6 – 4(4) + 30 ÷ 5 6 – 16 + 30 ÷ 5 −10 + 30 ÷ 5 20 ÷ 5 4 Karen 6 – 4(3 – 5)2 + 30 ÷ 5 6 – 4(–2)2 + 30 ÷ 5 6 – 4(−4) + 30 ÷ 5 6 + 16 + 30 ÷ 5 6 + 16 + 6 22 + 6 28

Answer 1

Matt
6 – 4(3 – 5)2 + 30 ÷ 5
6 – 4(–2)2 + 30 ÷ 5
6 – 4(4) + 30 ÷ 5
6 – 16 + 30 ÷ 5
−10 + 30 ÷ 5
20 ÷ 5
4
Karen
6 – 4(3 – 5)2 + 30 ÷ 5
6 – 4(–2)2 + 30 ÷ 5
6 – 4(−4) + 30 ÷ 5
6 + 16 + 30 ÷ 5
6 + 16 + 6
22 + 6
28

That'll be easier to read

Answer 2

Wait so are they both wrong? Karen seems to be right.

Answer 3

Yeah, they're both wrong.

Answer 4

hold on let me solve it real quick

Answer 5

So is the 2 by (3-5) an exponent?

Answer 6

hmmm I solved it and I got 28 just like Karen did except I soled it a different way.....

Answer 7

solved**

Answer 8

she got the right answer r u sure she is supposed to be wrong??

Answer 9

Thing that's confusing me is the 2 an exponent? Like this
\[4(3-5)^{2}\]or is it\[4(3-5)2\]Kind of weird of how they put the 2 at the end.

Answer 10

it is but i think its just a 2 and ur supposed to multiply the 2 but the number u get after u get done with the parenthesis

Answer 11

Okay so Karen's answer is right i guess but they both solved it the wrong way. How do I explain how they both should have solved it?

Answer 12

hmmm well i just resolved it a different way and got four........ im not really sure bc im good at solving things just not explaining the differences... what type of math is this?

Answer 13

The answer to the equation is -4. Neither one of them are correct.

Answer 14

hmmmm well then idk haha sorry :/

Answer 15

Ugh.... I'm in Calculus III and this 'simple' problem is making me mad.

Answer 16

wow haha im in algebra 2 honors i should know this too

Answer 17

It's irritating! It should be so simple for me to identify their problem and just explain what they need to do to solve it correctly!!

Answer 18

it is really irritating... i hate thatthey have to make math problems so confusing.. this is why i like science!

Answer 19

Okay let me think I know you have to use PEMDAS for this...........

Answer 20

yea that's what i used.....

Answer 21

Thats what I used too

Answer 22

Okay well its 11:13 here and i got to get up early for school so im gonna go. Sorry i couldn't be of much help yontoo618......

Answer 23

Same here but I'm staying I'm gonna figure this out otherwise its gonna bother the heck out of me.

Answer 24

Its no big deal :) I'll figure it out some way or another!

Answer 25

@Lexieloo

Answer 26

WAIT you said answer was -4 right?

Answer 27

Haha ok well bye then :) Talk to you some other time @yontoo618 :)

Answer 28

Wow that's WAY TOO much math for me... Im more of a Science/English type of girl

Answer 29

Haha, yes the answer is -4.

Answer 30

Nvm thought you would get -4 but forgot to times a negative

Answer 31

Oh

Answer 32

If you distribute the - from the -4. Then you would get 4*(2)*-2=-16. Then do 30/5=6. Add the 2 6's to get 12. Then -16+12=-4.
