^QZ ALGEBRA. 



2. Add all the numerators together, and under the sum 

 write the common denominator, and it will give the sun^ 

 pf the fractions required. 



EXAMPLES. 



X. Having — and ~ given, to find their sum." 





Here '^•^ ^ > the numerator^. 



And 2X3^^*6 the common denominator, 



?X 2X Cx 



Therefore --- +-— zz=^ is the sum required. 

 006 • 



2. Having -j-y -j- and -- given, to find their 6Un>y 



aXdXf=: adf ^ 

 Pere cX^by^f z=z chf > the numerator^. 

 eXhXd := ebd J 



And bXdXf = ^^ the common denominator. 



Therefore -rir+'-^^T+'Tir^^ ij/ ^ — > ^^^ sum 



^df hdf hdj bdf 



required. 



3. Let a —— and ^-|- - — be added together. 



* ^ ; ^ , > the numerators. 





And ^X*^ = ^^ the common denominator. 

 Therefore a — ^ — la_l — ^ — ^ — Li_L —
