Adding intergers Study guides, Class notes & Summaries

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,....

When trying to solve one of the word problems, what is the first thing you should look for and do? - ANSWER Look for buzzwords so you can identify what process the word problem requires What are some buzzwords for subtraction? - ANSWER difference minus take away What are some buzzwords for multiplication? - ANSWER product times double When working a problem you should pay close attention to all the whats in the body of the paragraph? - ANSWER numbers and figures When you identify...

Adding with same denominator correct answer: (a/b)+c/b)=((a+c)/b) Subtracting with same denominator correct answer: (a/b)-(c/b)=((a-c)/b) Adding with different denominator correct answer: (a/b)+(c/d)=((ad)+(cb))/bd Subtracting with different denominator correct answer: (a/b)-(c/d)=((ad)-(cb))/bd Multiplying Factors correct answer: (a/b)*(c/d)=(a*c)/(b*d) Dividing Factors correct answer: (a/b)/(c/d)=(ad)/(bc) Factoring numbers correct answer: a(c/d)= a+(c/d)= (ad+c)/d ...
