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: ab=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
