OpenStudy (jango_in_dtown):

use BODMAS rule.

OpenStudy (helper2197):

what is bodmas can you show me please i only have 10 mins

OpenStudy (jango_in_dtown):

first the brackets will work

OpenStudy (jango_in_dtown):

so -12/3.(-8+16-6)+2

OpenStudy (welshfella):

BODMAS in UK = PEMDAS in the USA.

OpenStudy (stellabella146):

Parentheses Exponents: \[x ^{2}\] Multiply/Divide Add/Subtract. Parentheses first then Exponents the Multiply or Divide it depends on which comes first on the left side. Then Add or Subtract same rules with Multi and Divide

OpenStudy (helper2197):

ok i get that but i always get confused and mess up

OpenStudy (helper2197):

-12 ÷ 3 · (-8 + (- 4² )-6) +2 -12 ÷ 3 · (-8 + (- 16 )-6) +2 im stuck after this

OpenStudy (welshfella):

-12 / 3 *(-8 + (-4)^2 - 6) + 2 first do the 'inside' bracket first = -12 / 3 *(-8 + 16 - 5) + 2 Now the other parentheses = -12 / 3 *(2) + 2 Now work out 3 * (2) = 6

OpenStudy (welshfella):

= -12/6 = 2 NOw do the division and finally add the 2.

OpenStudy (helper2197):

so the answer is 2

OpenStudy (welshfella):

* -12/6 + 2 I should have written

OpenStudy (welshfella):

No first do the division -12/ 6 then add the 2

OpenStudy (welshfella):

division is done before add

OpenStudy (helper2197):

so the answers 4

OpenStudy (welshfella):

-12/6 = 2 was a typo Not 4 -12 /6 is not = 2

OpenStudy (helper2197):

so the answers 2

OpenStudy (welshfella):

a negative divided by a positive gives a negative result.

OpenStudy (helper2197):

so - 2

OpenStudy (welshfella):

-12/6 = -2 right?

OpenStudy (welshfella):

now add 2 to that -2 + 2 = ?

OpenStudy (helper2197):

and did you mean to put 5 or 6

OpenStudy (helper2197):

-4

OpenStudy (welshfella):

NO

OpenStudy (welshfella):

-4 is the result of -2 - 2 NOT -2 + 2

OpenStudy (helper2197):

so it a postive

OpenStudy (helper2197):

so 4

OpenStudy (welshfella):

No helper. You really ought to study the arithmetic involving negative numbers. - 2 + 2 = 0

OpenStudy (helper2197):

oh can you sum it all up for me please
