Test 2

Math 100. Exploring Mathematics.

Review for test 2

Test 2 will be on chapters 3 and 4 and will contain 5 problems (one will be a list of true/false questions; some will only require a short calculation; some will require longer calculation, more creativity, and/or ask for an explanation). Review the following topics/problems:

Place value: integers and decimals
Bases other than 10 (convert numbers from one base to another, perform addition/subtraction in another base, word problems)
Divisibility (important terms: divides, divisible by, factor, divisor, multiple)
Prime factorization, GCD (aka GCF), LCM
Number sets (definitions, examples, notations, set inclusions)
Pattern problems (how many dots/squares/etc. are there in the n-th figure)
Sums of consecutive (even/odd/all) integers in a certain range
Word problems that can be solved using equations or other algebraic thinking

Note: you may have noticed that the book contains a lot of investigations on algebra tiles. We did not do any of those and therefore algebra tiles will NOT be on the test.
