@jhonyy9

OpenStudy (kg1975):

96÷{-3*[32-(2+2)^2]}

OpenStudy (kg1975):

@jhonyy9

jhonyy9 (jhonyy9):

yes what is the first step - how you think ?

OpenStudy (kg1975):

uhmm.... perenthesis? 2+2?

jhonyy9 (jhonyy9):

exactly - and after this ?

OpenStudy (kg1975):

idk...

jhonyy9 (jhonyy9):

so 2+2=?

OpenStudy (kg1975):

4

jhonyy9 (jhonyy9):

ok. and than you check this parentheses on the right corner on the top has a little 2 what mean this ?

OpenStudy (kg1975):

muliply. something 2 times?idk what

jhonyy9 (jhonyy9):

no there is a sign of ^ do you know it ?

jhonyy9 (jhonyy9):

in front of this 2

OpenStudy (kg1975):

nope never learned it before thats why i needed help.. DX

jhonyy9 (jhonyy9):

so this sign of ^ mean exponent

jhonyy9 (jhonyy9):

ok. ?

OpenStudy (kg1975):

ok

jhonyy9 (jhonyy9):

and this mean that the resulted 4 you need push it on exponent,power of 2 how many will result ?

OpenStudy (kg1975):

4*4?

jhonyy9 (jhonyy9):

yes exactly

OpenStudy (kg1975):

16

jhonyy9 (jhonyy9):

great so now you get the result from this parentheses what is the next step ?

OpenStudy (kg1975):

so now i have 96÷{-3*[32-16]} so im guessing 32-16?

jhonyy9 (jhonyy9):

yes this is the next step sure

OpenStudy (kg1975):

32-16=16

jhonyy9 (jhonyy9):

correct and now ?

OpenStudy (kg1975):

uhh 3*16?

jhonyy9 (jhonyy9):

attention please there not is just 3

OpenStudy (kg1975):

ohh -3*16

jhonyy9 (jhonyy9):

yes

OpenStudy (kg1975):

still 48 because the 16 is bigger than the -3

OpenStudy (kg1975):

right?

jhonyy9 (jhonyy9):

3*16=48 but there is minus 3 time 16 so how many will result ?

OpenStudy (kg1975):

-48?

jhonyy9 (jhonyy9):

yes sure this is easy

OpenStudy (kg1975):

soo ik 98÷48 is 2 but since the 48 is - does that make it -2?

OpenStudy (kg1975):

or no

jhonyy9 (jhonyy9):

attention please there not is 98

OpenStudy (kg1975):

oops 96! i mean 96!

jhonyy9 (jhonyy9):

yes there is 96 divide by -48 = ?

OpenStudy (kg1975):

im guessing -2? because ik 96 divide 48 is 2 but isnt the 2 a -2?

jhonyy9 (jhonyy9):

so the right answer is -2 bc. you know that 96 = 48*2 so 96/48 = 2 but there you need divide 96 by -48 so thii is equal -2 bc. -2*(-48) = 96 bc. you know that minus *minus = +

jhonyy9 (jhonyy9):

this is understandably now for you ?

OpenStudy (kg1975):

yes! can u help me with another?

jhonyy9 (jhonyy9):

yes just post it on the open question column and tag me there please
