15 - 7 + 0 + 2 = 7 + 2 = 7 + 2 = 10 8 + - 5 - 2 = 8 + - 5 - 2 = 8 - 5 - 2 = 3 - 2 = 1(7 - 2 ) + (1 + 4 - 5 ) = (7 - 2 ) + (1 + 4 - 5 ) = 5 + (6 - 5 ) = 5 + = 5 + = 5 = 5

15 - 7 $\frac{3}{5}$ + 0 + 2 $\frac{7}{8}$ = 7 $\frac{2}{5}$ + 2 $\frac{7}{8}$ = 7 $\frac{16}{40}$ + 2 $\frac{35}{40}$ = 10 $\frac{11}{40}$

8 $\frac{5}{12}$ + $\frac{5}{6}$ - 5 $\frac{3}{4}$ - 2 $\frac{1}{2}$ = 8 $\frac{5}{12}$ + $\frac{10}{12}$ - 5 $\frac{9}{12}$ - 2 $\frac{6}{12}$ = 8 $\frac{15}{12}$ - 5 $\frac{9}{12}$ - 2 $\frac{6}{12}$ = 3 $\frac{6}{12}$ - 2 $\frac{6}{12}$ = 1

(7 $\frac{4}{9}$ - 2 $\frac{3}{10}$ ) + (1 $\frac{7}{9}$ + 4 $\frac{2}{9}$ - 5 $\frac{1}{2}$ ) = (7 $\frac{40}{90}$ - 2 $\frac{27}{90}$ ) + (1 $\frac{14}{18}$ + 4 $\frac{4}{18}$ - 5 $\frac{9}{18}$ ) = 5 $\frac{13}{90}$ + (6 - 5 $\frac{9}{18}$ ) = 5 $\frac{13}{90}$ + $\frac{9}{18}$ = 5 $\frac{13}{90}$ + $\frac{45}{90}$ = 5 $\frac{58}{90}$ = 5 $\frac{29}{45}$
