Adding with same denominator Answer:(a/b)+c/b)=((a+c)/b)
Subtracting with same denominator Answer:(a/b)-(c/b)=((a-c)/b)
Adding with different denominator Answer:(a/b)+(c/d)=((ad)+(cb))/bd
Subtracting with different denominator Answer:(a/b)-(c/d)=((ad)-(cb))/bd
Multiplying Factors Answer:(a/b)(c/d)=(ac)/(b*d)
Dividing Factors Answer:(a/b)/(c/d)=(ad)/(bc)
Factoring numbers Answer:a(c/d)= a+(c/d)= (ad+c)/d
Intergers Answer:{...,−3,−2,−1,0,1,2,3,...}
Real Numbers Answer:All numbers that are on number line. Integers plus fractions,
decimals, and irrationals
PEMDAS Answer:Parentheses, Exponents, Multiplication, Division, Addition, Subtraction
Percentages Answer:part = (percent / 100) x whole
percent of change Answer:((New value - old value)/old value) X 100
Distance from A to B Answer:√(x2 − x1)^2 + (y2 − y1)^2
Parallel and Perpendicular lines Answer:Parallel lines have equal slopes. Perpendicular
lines (i.e., those that make a 90∘90° angle where they intersect) have negative reciprocal
slopes: 𝑚1m1 .𝑚2=−1m2=−1.Parallel Lines (l ∥∥ m)
Mid-point of the segment AB Answer:M (𝑥1+𝑥2/2),(𝑦1+𝑦2/2)
Slope of the line Answer:(𝑦2−𝑦1)/(𝑥2-𝑥1)=𝑟𝑖𝑠𝑒/𝑟𝑢𝑛
Point-slope form Answer:y-y1=m(x-x1), where (x1,y1) is any point on the line and m is the
slope of the line
Slope-intercept form Answer:y=mx+b, where m is the slope and b is the y-intercept of the
line.
Factoring Answer:"FOIL"
(𝑥+𝑎)(𝑥+𝑏)(x+a)(x+b)=
𝑥2+(𝑏+𝑎)𝑥+𝑎𝑏=
