Answer 3

Medal will be awarded

Answer 4

Let's try to visualize it: \[5+(\sqrt{15}+6)=(5+\sqrt{15})+6\]

Also: these are the properties (in the right order):

a+(b+c)=(a+b)+c
a+b=b+a
a(b+c)=ab+ac
a(bc)=(ab)c

Can you see it now?

Also: you need to learn these properties to be able to answer future questions...

Answer 5

I've never been showed like this! Thank you so much!

Answer 6

They only try to make it difficult, by using sentences...
Formulas are much clearer here!

Answer 7

What would closure property look like?

Answer 8

Closure property (addition): if a and b are real numbers, then a+b is also real.
Closure property (multiplication): if a and b are real numbers, then ab is also real.

Answer 9

Thank you thank you thank you!
