I need help on some math problems?

Question

ok...find each value of each expression (directions)

6(6) ÷ 2 X 9

got 18

6(6 ÷ 2 X 9)

got 2

some how i think my answers are way off..........help? :'(

Answer 1

Order of operations:

1 - parentheses

2 - multiplication and/or division (in order as they appear)

3 - addition and/or subtraction (in order as they appear)

For your 1st problem, you'd start with the 6(6) then proceed from left to right -> 6(6) = 36 -> 36/2 = 18 -> 18 x 9 = 162

2nd problem, you start with what's in parentheses -> 6/2 = 3 -> 3 x 9 = 27 -> 6(27) = 162

Answer 2

Well from the first i for 36 (divided by) 18 which is 2

And for the second i got 6 (multiplied by) 27 which is 162

Then again, mine may be off as well

Good luck, if all else fails leave it and ask your teacher to help you :)

Answer 3

I got 162 for the first one and for the second one I got 162. I used the PEMDAS thing.

Parenthesis

Exponents

Multiplication

Division

Addition

Subtraction

That is the order of operations that I learned like 2-3 years ago.

Answer 4

thats because.

FIRST QUESTION:    

6(6) first. = 36 divided by 2 would be 13 TIMES 9 is 162

SECOND QUESTION:

Parenthesis  ALWAYS first. (brackets are before them though.) so 6 divided by 2 is 3 times 9 is 27. times 6 is 162

1. =162

2. =162

Answer 5

both answers are 162:)

Answer 6

6(6) -2x9

would be (6 X 6) divided by (2x9) so 36 divided by 18 which is  2.....



6(6-2x9)

would be 2 x 9 equals 18 then divide it by 6 equals 3 then x 6 would be 18.
