Примеры:
1)(7-4+3+1)+(3*6*2*3 - 5*4*2*3 + 1*4*6*3 + 2*4*6*2) / (4*6*2*3) = 7+(108-120+72+96)/144 = 7+(156/144) = 8 1/12.
2)(9-8+7-5) + (2*3*4*6 - 1*5*4*6 + 1*5*3*6 * 1*5*3*4) /(5*3*4*6) = 3 + (144-120+90-60)/360 = 3+54/360 = 3 3/20 = 3 15/100 (3,15)
3)(6-5+2+9-7) + ((5/8-1/2) - (3/4-1/6) + (5/8 - 1/3)) = 5 + ((5/8-4/8) - (9/12-2/12) + (15/24-8/24)) = 5 + (1/8 - 7/12 + 7/24) = 5 + (3-14+7)/24 = 5 - 4/24 = 5 - 1/6 = 4 5/6.
4)(5-2+6-7+6) +(1/30 - 3/5 - 2/15) - ( 1/4 - 11/12) = 8 + (1-18-4)/30 - (3-11)/12 = 8 - 21/30 + 8/12 = 8 - (7/10 - 2/3) = 8 - (21 -20)/30 = 8 - 1/30 = 7 29/30.
