Question

The money Noreen earned babysitting can be shown in the expression:


3(15.75) + 4.25(3 + 4 + 5)



What would happen if you did NOT use the correct order of operations (PEMDAS) to solve this problem?

In your answer: You will have two calculations, 1 following each step using PEMDAS and 1 solving with out PEMDAS. Explain what you found.

Answer 1

@GabeBae

Answer 2

I'll solve it using PEMDAS and you solve it without using PEMDAS just start from the left and solve without doing anything

Answer 3

ok,

Answer 4

so I just don't solve a thing?

Answer 5

PEMDAS = Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction
\[3(15.75) + 4.25(3 + 4 + 5)\]
Parenthesis first
\[3(15.75) + 4.25(12)\]
Multiply second
\[47.25 + 51\]
Last you add
\[98.25\]

Answer 6

O! So I solve WITHOUT using parentheses?

Answer 7

No.. you have to solve just start solving from the left

Answer 8

No

Answer 9

ok

Answer 10

Solve without using PEMDAS

Answer 11

How?

Answer 12

I've already solved it for you using PEMDAS
It asks you to solve using PEMDAS and to solve without using PEMDAS

Answer 13

3+4.25?

Answer 14

OH OK.

Answer 15

3+15.75 + 4.25 +3 +4 + 5?

Answer 16

yea i'm a pain. sorry

Answer 17

\[3(15.75) + 4.25(3 + 4 + 5)\]
\[47.25 + 4.25(3+4+5)\]
\[51.5(3+4+5)\]
\[51.5(12)\]
\[618\]
I don't know if I did it correctly
3rd step confused me

Answer 18

Either way, without using PEMDAS you'll still get the wrong answer
and nah it's fine you're not a pain in the retrice

Answer 19

XD

Answer 20

It blurred it out :')

Answer 21

LOL

Answer 22

I'm so funny
I know..

Answer 23

Buty how are you solving WITHOUT using Pedmas?

Answer 24

You just work from the left and solve it straight forward

Answer 25

And where does 51 come in? I'm a clueless little one XD

Answer 26

You're technically solving it the wrong way

Answer 27

True, because parentheses is first

Answer 28

47.25 + 4.25 = 51.5

Answer 29

You're still doing the math correctly though :P
Just the way you're doing it is wrong makes the answer wrong at the end

Answer 30

Are you multiplying the 15 and 3?

Answer 31

yes
you start off from the left without using PEMDAS
I don't think it matters how you solved it as long as you didn't use PEMDAS

Answer 32

It asks you to solve using PEMDAS and without using PEMDAS

Answer 33

I think I understand it. But I'm still confused where the 51 comes in?

Answer 34

You add 47.25 and 4.25

Answer 35

With PEDMAS, right?

Answer 36

without PEMDAS

Answer 37

Read what it's asking you to do

Answer 38

Which one is without PEDMAS?

Answer 39

2nd one

Answer 40

ohhhhhhh

Answer 41

The first one I did at the top is using PEMDAS
then the one in the lower section is solved without using PEMDAS

Answer 42

Should I explain the difference in numbers without using PEDMAS?

Answer 43

If you want

Answer 44

What grade are you in?

Answer 45

Pre-School. Advanced Pre-School

Answer 46
