Across:
1 Floating point system in which numbers are expressed as products consisting of a number between 1 and 10 multiplied by an appropriate power of 10.
4 The number that indicates how many times the base is used as a factor, 4 x 4 x 4 = 64, the ________ is 3, indicating that 4 is repeated as a factor three times.
5 A number that can be written in the form A + bi where a and b are real numbers and i = square root of -1.
6 Any equation that can be written in the form Ax + By + C = 0 where A and B cannot both be 0. The graph of such an equation is a line.
7 A rectangular array of numbers or variables.
8 Any real number expressed in base 10 notation, such as 2.673.
9 The branch of mathematics that includes combinatorics, recusion, Boolean algebra, set theory, and graph theory.
10 A number that can be written as the ratio of an integer to a counting number; or more formally, a number that can be expressed as a ratio a/b where a and b are integers and b is not equal to 0.
11 A plane in which two coordinate axes are specified, two intersecting directed straight lines, usually perpendicular to each other, and usually called the x-axis and y-axis. Every point in a ______________ can be described uniquely by an ordered pair of numbers, the coordinates of the point with respect to the coordinate axes.
12 The sequence of numbers beginning with 1,1, in which each number that follows is the sum of the previous two numbers, 1, 1, 2, 3, 5, 8, 13, 21,...
13 A type of transformation that moves every point by the same distance in the same direction, in a geographic map, moving a given distance due north.
14 A letter used to represent one or more numbers in an expression, equation, inequality, or matrix.
15 A mathematical relation that associates each object in a set with exactly one value.
16 A number (as 1, 5, 14) that is used in simple counting and that indicates how many elements there are in a set.
17 A set of elements ordered so that they can be labeled with consecutive positive integers starting with 1; 1, 3, 9, 27, 81. In this __________ 1 is the first term.
18 A number designating the place (as first, second, or third) occupied by an item in an ordered sequence.
20 A method of constructing a valid argument, using deductive reasoning.
Down:
2 A way of representing a number that shows the sum of each digit multiplied by the appropriate positive power of 10 and the units digit; 3451 as 3 x 1000 + 4 x 100 + 5 x 10 + 1
3 A type of transformation that turns a figure about a fixed point, called the center of ________.
10 A type of transformation that flips points about a line, called the line of __________
16 The mathematics of change and motion. The main concepts of ________ are limits, instantaneous rates of change, and areas enclosed by curves.
19 A comparison of two numbers or quantities, 4 to 7 or 4 : 7 or 4/7.
