OpenStudy (yamyam70):

okay, try this one for me, very easy, 3 ( x + y ) = ?

OpenStudy (anonymous):

3x 3y

OpenStudy (yamyam70):

whoops, forget the signs :) signs are used to seperate terms :)

OpenStudy (anonymous):

or 3xy

OpenStudy (yamyam70):

okay, not bad, but still wrong. 3x + 3y is the correct answer, we don't combine digits with different letters :) hope this clears your anxiety a bit :)

OpenStudy (anonymous):

ohhh ok ...got it yes and thank you bunches :D

OpenStudy (yamyam70):
