Rational Number Diagram
a real number that can be written as a fraction or decimal. It terminates or repeats.
Rational Numbers
two different numbers that have the same absolute value
Opposite Numbers
the set of numbers less than zero, numbers to the left of zero on the number line
Negative Numbers
The distance between a number and zero on the number line
Absolute Value
3/8 + (-1/2)
-1/8
positive and negative whole numbers
Integers
two numbers whose sum is zero
Additive Inverse
the set of numbers greater than zero, numbers to the right of zero on the number line
Positive Numbers
Absolute value can never be
Negative
1 3/8 - (-7/8)
2 1/4
numbers that begin with 0 and reaching infinity
Whole Numbers
a pair of numbers whose sum is zero
Zero Pair
Sing the rational numbers song
Same sign add and keep, different signs subtract. take the sign of the highest (absolute value) then you'll be exact...
Say the following problem in mathematical terms:
- l 3 l
the opposite of the absolute value of 3
7.6 - (-10.1)
17.7
numbers that begin with 1 and reaching infinity. Also known as "counting numbers"
Natural Numbers
Solve: 5 - (-3)
8
the rule when there are different signs?
Different signs, subtract and take the sign of the highest absolute value
l -10 l + l 15 l
25
-10.7 + -3.5
-14.2
fractions or numbers that DO NOT terminate or repeat; they keep going on with different digits
Irrational Numbers
Solve: 6 + -15
-9
the rule for same signs
Same signs, add and keep
- l -2568 l
-2568
the difference between irrational and rational number
irrational repeats with different numbers; they do not terminate or repeat. rational numbers terminate or repeat.
