2 variables can have the same value. If a + b = 2, you would not rule out the possibility of 1+1 as your answer just because one is called a and the other is called b. -surr Not the quote! Anyways, since you're resorting to that level, I'm done commenting to you regarding this matter. <_< I'm not here to prove your intelligence or mine.
As far as I know, a variable is simply a letter used to represent a number value in an expression or an equation. Unless the definition of a variable changes in higher mathematics (precalculus, calculus, multi, etc.) two different variables (a and b) can have the same value. If it does change...ignore me -^_^ I'm only in 10th grade, what do I know -sweat
Me either.. i just put this quote because it alaways make me laugh and albert einstein was great by this... for a genius who never khnow how to do math i can say that it just awesome ( if i remeber it was his wife who do all his math for him)..isn't ironic?
One is great not by skills but by the talent in association, Einstein is great because he deviced the beautifully simple E=mc^2 associating energy, mass and speed of light in a simple relationship (which still holds to this day)
I believe it the question is not convey properly. ( I forgot most of my proves in discrete math...hehe...gave it back to the prof after the exam) I think we have to use the "prove of contradiction" in match/ Hypothesis: a=b; suppose a = 4; b=3; (as stated in the question) Proof: a=b 4a=4b should have the same value substituing the values we have: 16=12; therefore it is trival and incorrect// It goes something like that in discrete math ...hehe
