Question

What is the value of the expression?

6 • [(32 − 8) ÷ 4 + 2]

Answer 1

@butterflydreamer

Answer 2

solve what's in the brackets first!
(32 - 8) = ?

Answer 3

Order of operations say to do parentheses first.

Answer 4

24

Answer 5

Good and now 24 divided by 4 = ?

Answer 6

= 6

Answer 7

correct! Now add 2 .
6 + 2 =?

Answer 8

=8

Answer 9

yep and now, multiply by 6 and you're done :)

Answer 10

can you help me with a few mor like this

Answer 11

so the answer is 78

Answer 12

Sure. I've noticed that you've been posting similar questions though. Just remember the order of operations and BODMAS and you'll be fine :)

And that is not quite the answer.
6 times 8 = ?

Answer 13

oh = 48

Answer 14

im sorry

Answer 15

that's correct :)
Also, if you don't understand BODMAS, it's the same as PEMDAS

<- super helpful reference with order of operations!

Answer 16

ok so you can help me with two more qestions right

Answer 17

BODMAS was before we added exponents to the mnemonic

Answer 18

Which placement of grouping symbols in the expression gives it a value of 22?

3 • 4 – 2 + 5 +7

A.
3 • [4 – (2 + 5) + 7]

B.
(3 • 4) – [2 + (5 + 7)]

C.
[(3 • 4) – 2] + (5 + 7)

D.
3 • (4 – 2) + (5 + 7)

Answer 19

thats the nest one

Answer 20

Try each choice using the correct order of operations, and see which one gives you the answer you need.

Answer 21

ok

Answer 22

What does the O mean in BODMAS?

Answer 23

The way to do a problem like this is to do one step at a time and writing everything else each step. Of course, you need to follow PEMDAS for each step.

6 • [(32 − 8) ÷ 4 + 2] =

= 6 • [24 ÷ 4 + 2]

= 6 • [6 + 2]

= 6 • 8

= 48

By writing everything each step, you don't forget any operation.

Answer 24

Also, it is important to understand PEMDAS properly.
Most people don't know how it works.

Answer 25

@jpharper

Let's work through each choice of the second problem.

Answer 26

ok

Answer 27

A.
3 • [4 – (2 + 5) + 7] =

Innermost parentheses first:

= 3 • [4 – 7 + 7]

We still have the square parentheses, so we do that next.

Answer 28

ok

Answer 29

Inside the square brackets, we have a subtraction and an addition.
In PEMDAS, AS means addition, Subtraction.
Those two operations are the same level of priority, so we do them in the order they appear from left to right.

= 3 • [-3 + 7]

= 3 • 4

= 12

Answer 30

this is the answer [(3 • 4) – 2] + (5 + 7)

Answer 31

This is what I meant by understanding PEMDAS properly.
Do operations of each line before the next line below.

P - parentheses
E - exponents
MD - multiplications and divisions in the order they appear from left to right
AS - additions and subtractions in the order they appear from left to right

Answer 32

Many people think that PEMDAS means doing the operations in the order below, but that is incorrect.
P - parentheses \
E - exponents \
M - multiplications \
D - divisions / The PEMDAS shown to the left is incorrect.
A - additions /
S -subtractions /

The correct order is what I wrote in the previous response above with MD in one line and AS in one line.

Answer 33

Yes, you are correct.
