We have at least four times as many chairs as tables. The number of chairs c is at least four times the number of tables t. Hence c 4t. Fill in the blanks. These statements follow from the quadratic formula.

## Description:

There are 6 n equally likely outcomes; we show that in half of them the sum is even. For each of the 6 n1 ways to roll the rst n 1 dice, there are six ways to roll the last die, and exactly three of them produce an even total. Probabilities for the sum of two rolled dice. The numbers x and 14 x are equally likely to be the sum of the num- bers facing up on two dice. Whenever i, j are two dice rolls that sum to x, the numbers 7 i and 7 j are two dice rolls that sum to 14 x, since 1 i 6 implies that 1 7i 6. Furthermore, the transformation is its own inverse. This establishes a bijection between the set of ordered pair dice rolls summing to x and the set of ordered pair dice rolls summing to 14 x, so the two sets are equally likely when the individual ordered pairs are equally likely rolls.

This survey of both discrete and continuous mathematics focuses on the logical thinking skills necessary to understand and communicate fundamental ideas and proofs in mathematics, rather than on rote symbolic manipulation. Coverage begins with the fundamentals of mathematical language and proof techniques such as induction ; then applies them to easily-understood questions in elementary number theory and counting; then develops additional techniques of proofs via fundamental topics in discrete and continuous mathematics. Topics are addressed in the context of familiar objects; easily-understood, engaging examples; and over stimulating exercises and problems, ranging from simple applications to subtle problems requiring ingenuity. Numbers, Sets and Functions. Language and Proofs.
