Do you know what 25 times 4 is?
OpenStudy (mertsj):
I guess not.

easier if you rewrite it as
\[25\times 4\times 22\] because \(25\times 4=100\) and it is simple to multiply by \(100\)

rewrite what mate?
OpenStudy (anonymous):
\[25\times 22\times 4\] as \[25\times 4\times 22\] via the commutative property of multiplication

ohh okay
OpenStudy (the_fizicx99):
Commutative property of multiplication means no matter what way you put it, its still going to give you the same result. i.e 22 * 25 * 4 will be the same as 4 * 25 * 22
So by multiplying 25 * 4 = 100 * 22 will no change your result in anyway

really?
OpenStudy (texaschic101):
commutative property basically states that you can move your numbers around and still get the same answer.
25 x 22 x 4....It would be easier to write it like this...25 x 4 x 22 because 25 x 4 = 100
and 100 x 22 = 2200.
OpenStudy (the_fizicx99):
Yes! @stolenaxis43
OpenStudy (the_fizicx99):
This only apply's to adding and multiplying. 2 + 3 = 5 3 + 2 = 5
4*5 = 20
5*4 = 20

okay now i get it thank you um... lad or lass?
