Explicación paso a paso:
A. 15/5-6:3+49/7-22/2 = 3-2+7-11 = 1+7-11 = 8-11 = -3
B. [36/(-4)-3*2]/(-2-4+1) = (-9-6)/(-6+1) = -15/(-5) = 3
C. (18/3+8/2-5*2)*(4+5-3) = (6+4-10)*(9-3) = (10-10)*6 = 0*6 = 0
D. 6+[7-5-(-2)+(-4)] = 6+7-5+2-4 = 13-5+2-4 = 8+2-4 = 10-4 = 6
E. (64:8-25/5)*2-(16/4+27/9)/7 = (8-5)*2-(4+3) = 3*2-7 = 6-7 = -1
F. (5+3)/2-(7-4)/3 = 8/2-3/3 = 4-1 = 3
G. 6/(2+1)-[1+(2*3/6)*7]+7 = 6/3-(1+6/6*7+7) = 2-(1+1*7+7) = 2-(1+7+7)=2-(8+7)= 2-15 = -1
H. [6*(4-6/2)]-[2-(1-10)/3] = [6*(4-3)]-(2+9/3) = (6*1)-(2+3) = 6-5 = 1
I. (1-7)/(2-4)+(12-10)/(1-2) = -6/(-2)+2/(-1) = 3+(-2) = 3-2 = 1
J. 4-6/(6-4)-[16/(9-1)-3] = 4-6/2-(16/8-3) = 4-3-(2-3) = 1-(-1) = 1+1 =2
