Absolute
value is the distance of a number on the
number line from zero. The evaluation of an absolute value is always
positive. _{
}and _{
}The of a number is the number which when added to a given number would sum to be
zero. For example, given the number 5, the additive inverse would be
–5 since 5 + (–5)
= 0. The additive inverse is also called the Additive Inverse of a number.opposite of a number is
the number that when multiplied to a given number would result in a product
of positive 1.Multiplicative InverseFor example, given the number 5, the additive inverse would be since and
The as a factor. The exponent is attached to the base
, the single character
directly below the exponent and to the left unless a parenthesis is used.
If a parenthesis is involved, then
the exponent affects everything within the parenthesis.
Therefore, base_{

_{}.
The square root of a negative radicand is not a Real Number, since no
Real Number squared may equal a negative number. For example, _{}is
not a Real Number.The views and
