Would you guys help me with order of operations?
Like
[9+7x23-A(7x9)]3 the three is an exponent and A = 7
any help?

Parentheses first, then multiplication and division from leftto right, then addition and subtraction from left to right.

What about Exponents?

Its multiplication obviously...
Idk about brackets though... I forgot about them

No it isnt I remember Exponents being a whole diffrent thing o.o

Umm... Exponets symbolize the amount of times you multiply a number by itself.
I.e: 4^3= 4x4x4=16x4= 64

Ok, heres a pretty good question.

How can the environment affect evolution?

Its pretty simple if you've read about evolution stuff.

Hours, I don't think you understand the use of this thread.

This is not "Ask a question, you answer it" thread.

This is a thread for when someone is stuck on any question that is homework related. If you seriously don't understand, try harder to understand or just don't use this thread.

Kershner: Work inside then out. Parentheses first then take out the parentheses then multiply and divide left to right and before you start adding or subtracting you have to do the exponent.

Wait actually I think the exponents last because it's outside of the bracket.

Ok thanks Kengee
