 May18 comment what is the diffrence between a term , constant and variable in first order logic languages ?i will :) i use enderton's text . i will search for those online free texts :) thanx professor May18 comment what is the diffrence between a term , constant and variable in first order logic languages ?@PeterSmith , u r right but if you live in a village in egypt then the idea of getting one or two books to ckeck the definition is not practical! because this may require a long time to get this text !

May18 asked what is the diffrence between a term , constant and variable in first order logic languages ? May18 accepted prove that , $2+2+2+2+2+ \cdots= 1+1+1+1+1+\cdots$ May16 comment Under what conditions is a zero divisor element $a$ in commutative ring $R$ nilpotent?@HagenvonEitzen , didn't understand your point ! May16 comment Under what conditions is a zero divisor element $a$ in commutative ring $R$ nilpotent?@QiaochuYuan , nope , i meant conditions on the element itself ! May16 comment Characterizing units in polynomial rings $R[X]$@JasonDeVito , so how can we complete the proof now ?! May15 comment Characterizing units in polynomial rings $R[X]$@HagenvonEitzen what do u mean ? May15 comment Under what conditions is a zero divisor element $a$ in commutative ring $R$ nilpotent?math.stackexchange.com/questions/19132/… see this link , there is a comment in the second answer which deduce that an element is nilpotent from being zero divisor ! but i don't understand why this is true ! May15 asked Under what conditions is a zero divisor element $a$ in commutative ring $R$ nilpotent? May15 comment Characterizing units in polynomial rings $R[X]$@JasonDeVito , why $a_n b_m=0$ implies that $a_n$ is nilpotent ? can you explain this more plz ? May15 accepted Group theory between mathematicians and physicists? May15 asked How should we study maths? May10 asked Group theory between mathematicians and physicists? May8 asked What is the needed background to study tensors? May8 awarded Caucus May3 comment prove that $a_0$ is a unit and that $a_1 , a_2 , .. a_{n}$ are nilpotents in $R$ .it's not necessary that there is an inverse to $p_{n}$ ! May3 comment Under what conditions does a ring R have the property that every zero divisor is a nilpotent element?thanx , i think that i will come back to this question when i study these concepts in the future !
