Algebra, Numbers and Operations Flashcards
Product=
Multiply
Prime Number
Positive integer that is divisible ONLY by itself and 1
To find a common denominator…
Add the larger denominator to itself until all other denominators divide into it evenly
Finding DISTANCE for Motion Problems
Distance= Rate x Time
Even + Odd=
ODD
Work=
Rate x Time –> Work is usually 1 unit so… R=1/T
Quotient
Divide
Which integer is larger, 5/6 or 6/7?
6/7
Odd + Odd=
EVEN
Even + Even=
EVEN
Odd x Odd=
ODD
(X^2) - (Y^2)=
(X - Y) (X + Y)
Even x Odd=
EVEN
Even x Even=
EVEN
Intiger ZERO is…
Neither positive or negative, but it is EVEN
The remainder is r when P is divided by q…
P = qz + r, where z=quotient
Taking the square root of a fraction between 0 and 1…
a) Makes it smaller
b) Makes it larger
b) Makes it larger
Geometric Sequence Formulas
1st term: a
2nd term: ar^1
3rd term: ar^2
nth term: a(n)=ar^n-1
Sum of the first n terms: {a [1 - (r^n)]} / (1 - r)
r= common ratioWhat percent of Y is Z?
What (X) Percent (1/100) of Y is (=) Z?
(X) x (1/100) x Y = Z
What percent of 25 is 5?
What (X) Percent (1/100) of 25 is (=) 5?
(X) x (1/100) x 25 = 5 –> (25/100)X = 5 –> X= 20
Arithmetic Sequence Formulas
1st term: a + 0d 2nd term: a + 1d 3rd term: a + 2d nth term: a + (n - 1)d Sum of the first n terms: (n/2) x [2a + (n - 1)d] a= first term d= common difference
When the integer n is divided by 2, the quotient is U and the remainder is 1…
n= 2U + 1
An inequality (> or
Dividing or multiplying by a negative number
(X^a) x (X^b)=
X^(a+b)
(X^a)^b=
X^(ab)
