-50 - 4 ( (-10-4 (-3+1)^2 ) / (-2) )

Answer 1

Can someone help me solve this step by step

Answer 2

anyone

Answer 3

What is -3 + 1 = ??

Answer 4

-2 but I dont get how to eliminate the brackets

Answer 5

It is in the bracket now..

What is the square of -2??

Answer 6

-50 - 4 ( (-10 - 4(-2)^2 ) / (-2) )

Answer 7

After this I am getting confused because dont we take the brackets out so it beccomes (-10-4+4)

Answer 8

but the answers ahve ( -10 -4(4)

Answer 9

I am just talking about the middle part

Answer 10

-50-4[(-10-4(-3+1)^2]
-54[-10-4(-2)^2]
-54[-10-4(4)]
-54(-10-16)
-54(-26)
1404

Answer 11

why is -54[-10-4(4)] the (4) in brackets dont they get removed

Answer 12

After the operation is done do we not remove the brackets also or do they stay? no matter what happends

Answer 13

\[ (-10-4 (-3+1)^2 ) / (-2) = \frac{-10-4(4)}{-2} = \frac{-26}{-2} = 13\]

Answer 14

I am just confused about the brackets, do we keep them and when do we take the brackets out ?

Answer 15

I dont know how to word my question but it is about the brackets and when we remove them ?

Answer 16

can u right ur equation clearly?? :)

Answer 17

Once the parenthesis are simplified you may remove them a replace them with multiplication.

Answer 18

In other situations you may also distribute to rid the parenthesis.

Answer 19

So, now the expression has become:

\[\huge \color{green}{-50 -4(13) = ???}\]

Answer 20

My question is how we get rid of the parenthesisi

Answer 21

Do we remove them after we add what ever is inside it

Answer 22

Yes..

Answer 23

yes.. if you can add whats inside

Answer 24

if not you may need to distribute or they could possibly be pointless

Answer 25

SO In this case -50 - 4 ( (-10-4 (-3+1)^2 ) / (-2) )

oncre the -3 and the 1 are added dont we remove the brackets to make it
-50 - 4 ( (-10-4 +2 ^2 ) / (-2) )

Answer 26

rather than multiplyingg

Answer 27

What is the inner most bracket in the expression??

Answer 28

(-3+1) is the inner most bracket

Answer 29

But it is having an exponent too...

so after adding -3 and 1 you cannot eliminate this bracket..

You will get:

\[(-2)^2\]

Now apply square..

Answer 30

keep the parenthesis until after you evaluate the exponent. When you do finally remove the parenthesis if there is a number directly next the the parenthesis it becomes multiplication.

Answer 31

Is that a rule keeping the parentsiis until the exponent has been evaulated

Answer 32

*parenthesis

Answer 33

yes!

Answer 34

have you ever been taught the order of operations?

Answer 35

In this case after taking the square also you cannot eliminate the brackets because there is a number outside too..

\[-4(-3+1)^2\]
\[= -4(-2)^2\]

\[= -4(4)\]

Now after multiplying you can eliminate the brackets...

Like:

\[-4(4)\]

\[= -16\]

Answer 36

Yea but not the rule of parenthesis

Answer 37

-50 - 4 ( (-10-4 (-3+1)^2 ) / (-2) )

\[-50-4*(\frac{-10-4(-3+1)^2}{-2})\]

Answer 38

Thank you so much that was exacly what i was confused about
