Multiplicative Property of EqualityIf two REAL NUMBERs are equal in
value, for example, if a=b,then when they are multiplied by another
real number, for example, c,the SUMs will be equal. In EQUATION
form, it looks like this: if a=b,then ac=bc.

Multiplicative Property of ZeroIf any REAL NUMBERis multiplied by zero,
the sum will equal zero.

multiplierAny number that is being multiplied. For example, in 3 ×4, 3 is the
multiplier.

natural numberBeginning with the number 1, any positive, WHOLE
NUMBER. For example, 3 is a natural number, –3 is not a natural
number, and 0.3 is not a natural number. Natural numbers are also
called counting numbers.

negative numberAny number that is less than zero in value. A negative
number is indicated with the “–” sign.
nonagonA nine-sided POLYGON.
null set SeeEMPTY SET.
number The word numberis typically used to mean “REAL NUMBER.”
number lineA straight line that represents all of the numbers. It is drawn with
an arrow on the ends to show that it goes on indefinitely. Zero on the
number line is called the ORIGIN, with NEGATIVE NUMBERs marked
on points to the left of zero, and POSITIVE NUMBERs marked on points
to the right of zero.
numerator (divisor)The number in a FRACTIONthat is above the division
line. The number that divides the DIVIDEND. For example, in^1 – 2 , the
numerator is 1. In– 43 the numerator is 3, in –^78 the numerator is 7, in— 169
the numerator is 9, and in— 10097 the numerator is 97.

oblique angleAnyANGLE, whether acute or obtuse, that is not a RIGHT
ANGLE.
