FTCE General Knowledge Test Math
whole numbers ANS: the whole numbers and zero
natural numbers ANS: the counting numbers. 1, 2, 3, 4, 5, 6,...
irrational numbers ANS: real numbers that cannot be written as the ratio of two integers
exponent form ANS: a shorthand way of writing repeated multiplication.
write 46, 368, 000 in scientific notation ANS: 4.6368 x 10^7
write 0.00397 in scientific notation ANS: 3.97 x 10^-3
properties ANS: rules that apply for addition, subtraction, multiplication, or division of real numbers
types of properties ANS: commutative, associative, identity, inverse, distributive
commutative ANS: You can change the order of the terms or factors:
for addition: a + b= b + a
for multiplication: ab=ba
associative ANS: you can regroup the terms as you like
for addition: a + (b + c)= (a +b) + c
for multiplication: a(bc)= (ab)c
, Identity ANS: addition: a + 0= a
multiplication: a x 1= a
Inverse ANS: finding a number such that when added to the number it results in zero; or when
multiplied by the number, it results in 1.
addition: a+a=0
multiplication: a x (1/a)=1
Distributive ANS: a (b + c)= ab + ac
polygon ANS: a simple, closed, two-dimensional figure composed of line segments
Quadrilateral ANS: a polygon with four sides.
the sum of the measures of the angles is 360 degrees.
trapezoid ANS: a polygon with exactly one pair of parallel sides
isosceles trapezoid ANS: a quadrilateral in which the nonparallel sides are congruent
parallelogram ANS: a quadrilateral with two pairs of parallel sides.
the diagonals bisect each others, each diagonal divides the parallelogram into two congruent triangles,
both pairs of opposite sides are congruent, both pairs of opposite angles are congruent, and two
adjacent angles are supplementary.
rectangle ANS: a parallelogram with a right angle
rhombus ANS: a parallelogram with all sides equal in length
whole numbers ANS: the whole numbers and zero
