An Introduction to Proofs and the Mathematical Vernacular 1

This means learning the language and notation (symbols) which we use to express our reasoning precisely. But writing a proof is always preceded by finding the logical argume ...

Thus the number of subsets of {1, 2, . . . , n} is twice the number of subsets of {1, 2, . . . , n − 1}. This will give us the inductive st ...

Thus we assume that 1* 21 + 2 * 22 + ... + n*2n = (n-1) 2n+1 + 2, and show that 1* 21 + 2 * 22 + ... + n ...
