The complex numbers are a field How do i convince someone that $1+1=2$ may not necessarily be true I once read that some mathematicians provided a very length proof of $1+1=2$ Can you think of some way to It's a fundamental formula not only in arithmetic but also in the whole of math Is there a proof for it or is it just assumed?

49 actually 1 was considered a prime number until the beginning of 20th century Unique factorization was a driving force beneath its changing of status, since it's formulation is quickier if 1 is not considered a prime But i think that group theory was the other force. 1/8 1/4 3/8 1/2 5/8 3/4 7/8 英寸。 this is an arithmetic sequence since there is a common difference between each term In this case, adding 18 to the previous term in the sequence gives the next term In other words, an=a1+d (n−1)
