 15h revised If $a=b$ then $a+c=b+c$? added 35 characters in body 15h comment If $a=b$ then $a+c=b+c$? they are real numbers 15h revised Summation of $\binom{N}{K}$ added 17 characters in body 15h answered Summation of $\binom{N}{K}$ 16h comment If $a=b$ then $a+c=b+c$? so two things are equal if the have the same value? 16h comment If $a=b$ then $a+c=b+c$? Why can we replace $b$ with $a$ without altering the result? 16h revised If $a=b$ then $a+c=b+c$? edited body 16h revised If $a=b$ then $a+c=b+c$? edited body 16h revised If $a=b$ then $a+c=b+c$? edited body 16h asked If $a=b$ then $a+c=b+c$? 17h comment What are the differences in mental skills required to master abstract algebra and analysis?? This is just my personal experience and opinion, I don't state it as a fact. In my personal experience when I am familiarized with a mathematical topic I achieve the same level of proficiency at it (not that the level is high, just equal). 1d revised Prove that there is an integer a such that a is a primitive root modulo p^2 and a is relatively prime to n. [Hint: Use the Chinese Remainder Theorem.] edited body 1d comment Find all solutions of equation $x^{23}=5$ in $\Bbb Z_{23}$ 5 is indeed the only solution. 1d comment Prove that there is an integer a such that a is a primitive root modulo p^2 and a is relatively prime to n. [Hint: Use the Chinese Remainder Theorem.] Sorry, it was a typo, I fixed it. 1d revised Prove that there is an integer a such that a is a primitive root modulo p^2 and a is relatively prime to n. [Hint: Use the Chinese Remainder Theorem.] edited body 1d comment Find all solutions of equation $x^{23}=5$ in $\Bbb Z_{23}$ why is this tagged group theory when you are actually working in a field? 1d answered Prove that there is an integer a such that a is a primitive root modulo p^2 and a is relatively prime to n. [Hint: Use the Chinese Remainder Theorem.] 1d answered This question is from my discrete math. So far i have no idea how to solve it. Can anyone help me with this? 1d revised Every open map $f : \mathbb R \rightarrow \mathbb R$ implies added 13 characters in body 1d answered Every open map $f : \mathbb R \rightarrow \mathbb R$ implies
