TSIA2 STUDY GUIDES: MATH EXAM QUESTIONS WITH 100% CORRECT ANSWERS | GUARANTEED PASS | 2026 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)=(a*c)/(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, SubtractionPercentages - 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:
