Unlike Terms MULTIPLICATION
|
can multiply like and unlike terms
|
|
|
Natural Numbers
|
(counting numbers) {1,2,3,4,...}
|
|
|
Whole Numbers
|
(not counting numbers) {0,1,2,3,...}
|
|
|
Rational Numbers
|
any number that CAN be written as fractions/quotient
ex: 1/2,-7/3 |
|
|
(-) + (-) =
(lose) + (lose) = |
(-)
(lose alot) |
|
|
Dividing Fractions
|
- multiply it by its reciprocal
- reduce (cross division) - multiply across ex: flip the second fraction (reciprocal) (2/3)/(4/3)= (2/3)x(3/4) |
|
|
Irrational Numbers
|
any number that CAN NOT be written as fractions/quotient
ex: pi, square root of 2 |
|
|
Multiply Fractions
|
-reduce
-find common denominator (whatever u do to the bottom, u do to the top) -multiply across |
|
|
ORDER OF OPERATIONS
|
Parenthesis
Exponent Multiplacation Division Addition Subtraction **from left to right |
|
|
(+) + (+) = (+)
(win) + (win) = |
(+)
(win alot) |
|
|
(add & subtract real #s)
1. WHEN SIGNS ARE DIFFERENT? 2. WHEN SIGNS ARE SAME |
1. SUBTRACT THEIR ABSOLUTE VALUES (addition of the opposite) ex: a-b=a+(-b)
2. ADD KEEPING THE SIGN |
|
|
(multiply & divide real #s)
1. SAME SIGN? 2. DIFFERNT SIGN? |
1. answer POSITIVE ex: (+)(+)=(+) or (-)(-)=(+)
2. answer NEGATIVE ex: (+)(-)=(-) or (-)(+)=(-) |
|
|
Multiplicative Inverse
|
(reciprocal) ex: 2= 1/2, 1/7=7/1=7, -3=-1/3
|
|
|
Absolute Value
|
distance from zero
ex: |-5|= 5, |8|= 8 |
|
|
(+) + (-) =
(win) + (lose) = |
**(win or lose) depends on whichever has the larger sign
|
|
|
0/5 =
|
0
|
|
|
5/0=
|
undefined (we may never divide by 0)
|
|
|
1. (-4)^2 =
2. -4^2 = |
1.(-4)(-4)= 16 **(same sign = pos)
2. -(4)(4)= -16**(diff.sign = neg) |
|
|
Like Terms ADDITION/SUBTRACTION
|
can ONLY add or subtract(simplify) like terms
|
|
|
Integers
|
a member of the set of positive whole numbers, negative whole numbers, and zero
|
