Question

Вычисли удобным способом 42-(19+12)= (28+37)+12= 6*9+(27+26)= 8*7-(4*4+14)=

Answer 1

42-12+19=49

28+12+37=57

6*9+26+27=107

8*7-(16+14)=26

 

Answer 2

42 - (19 + 12) = 42 - 31 = 11

(28 + 37) + 12 = 65 + 12 = 77

6 * 9 + (27 + 26) = 54 + 53 = 107

8 * 7 - (4 * 4 + 14) = 56 - (16 + 14) = 56 - 30 = 26
