Expression
((7/9+2/3+(-13)/9)*(5/4*3/10+1/6)+3/5+(-1)/10)*10/5+4/5

  1. A sum containing 2 terms. The first term of the sum is equal to a quotient: dividend of the quotient is a product of 2 factors. The first factor of the product is a sum that comprises 3 terms. The first term of the sum is equal to a product comprising 2 factors. The first factor of the product is equal to a sum of 3 terms. The first term of the sum is a fraction: the top of the fraction is seven. The bottom of the fraction is nine. The second term of the sum is equal to a rational expression: the numerator of the rational expression is two. The denominator of the rational expression is three. The third term of the sum is a rational expression: the numerator of the rational expression is negative thirteen. The denominator of the rational expression is nine. The second factor of the product is a sum containing 2 terms. The first term of the sum is a rational expression: the top of the rational expression is a product of 2 factors. The first factor of the product is equal to a rational expression: the numerator of the rational expression is five. The denominator of the rational expression is four. The second factor of the product is three. The bottom of the rational expression is ten. The second term of the sum is equal to a quotient: dividend of the quotient is one. Divisor of the quotient is six. The second term of the sum is equal to a fraction: the top of the fraction is three. The bottom of the fraction is five. The third term of the sum is equal to a fraction: the numerator of the fraction is negative one. The denominator of the fraction is ten. The second factor of the product is ten. Divisor of the quotient is five. The second term of the sum is equal to a fraction: the top of the fraction is four. The bottom of the fraction is five.
  2. left parenthesis left parenthesis seven over nine plus two divided by three plus negative thirteen over nine right parenthesis times left parenthesis five divided by four multiplied by three over ten plus one fraction line six right parenthesis plus three over five plus negative one over ten right parenthesis multiplied by ten fraction line five plus four fraction line five;
