Math help..Last one I swear?

Question

-3 [-1 - 2(-1 - 1)] [-3(-2) - 1]

I got 108...

It seems rather large considering this is beginning of the year review stuff...But I may be wrong

*note* im not cheating...Im checking my answers and then re-working them until they are correct.

Answer 1

I used a calculator and got -37

Answer 2

it is -45

Answer 3

i got -45. i manipulated the numbers in the parenthesis first then the brackets then multiplied -3.

Answer 4

- 3 [ - 1  + 4 ] [ 5 ]

- 3 [ 3 ] [ 5 ]

- 45

Answer 5

Is it addition?:

= - 3(- 1 - 2[- 1 - 1]) + (- 3[- 2] - 1)

= - 3(- 1 - 2[- 2]) + (6 - 1)

= - 3(- 1 + 4) + 5

= - 3(3) + 5

= - 9 + 5

= - 4

Or is it multiplication:

= - 3(- 1 - 2[- 1 - 1])(- 3[- 2] - 1)

= - 3(- 1 - 2[- 2])(6 - 1)

= - 3(- 1 + 4)(5)

= - 3(3)(5)

= - 9(5)

= - 45

Answer: if addition then, - 4; if multiplication then, - 45

Answer 6

-45

Answer 7

it is -45. follow PEMDAS

do math first inside those in Parenthesis

then numbers in Exponents

then do Multiplication

Division

Addition
