math homework help... need smart people?

Question

Okay, it is on order of operations:
[4*(9+3*6)]-3
i tried it and i got 65 and i know that is wrong... help me please.

Actually, thanks for all of your help, but i figured out the answer and it is 105. Thanks, though

Answer 1

Well, order of operations is BEDMAS...so, you need to do what's in the brackets first. In your innermost bracket we have

9+3*6

BEDMAS says we multiply first, then add so we can break this down to

9+(3*6) which becomes 9+18 which is 27

so now your equation reads [4*(27)]-3

We still have stuff inside brackets, and all it is is multiplication.
4*27 = 108

now you're left with 108-3 which becomes 105


In case you didn't know, BEDMAS is:
Brackets
Exponents
Division
Multiplication
Addition
Subtraction

Answer 2

[4*(9+3*6)]-3
First do the multiplying inside the inner brackets
3 x 6 = 18
Now add within the inner brackets 9 + 18 = 27
Now multiply within the outer brackets 4 x 27 = 108
Now subtract the 3 108-3 =105

Answer 3

order is like this
first bracket
followed by multilication
division
adition
subtraction


in bracket
first is()
next{}
[]

in case these are not sufficient we use a bar above if this is present it is to be considered before ()

now try this [4*(9+18)]-3
=[4*27]-3
=108-3
=105

Answer 4

36+12+24-3
48+24-3
72-3
69

Answer 5

i think it's 285... im in sixth grade, so im pretty much just guessing. but i think so... wait... i agree with christine. good job christy! :)

Answer 6

I always learned it as PEMDAS...
