Answer 1

3*7 - 4*5 = 21 - 20 = 1
b) 6*(2+7)= 6*9 = 54
C) 10*6+12:3= = 60 + 4 = 64
d) 100-2*(13-7) = 100 - 2*6 = 100 - 12 = 88
e) 70-(25-4):7 = 70 - 21:7 = 70 - 3 = 67
f) 10*6+12:3+1= 60 + 4 + 1 = 65
g) 5*(4+7)-6*3= 5*11 - 18 = 55 - 18 = 37
h) 8*9-(5*4-2*7)-2= 72 - (20-14) -  2 = 72 - 6 - 2 = 72-8 = 64
i) 2*9:3+12*(17-4*3)= 18:3 + 12*(17 - 12) = 6 + 12* 5 = 6 + 60 = 66
j) 2*70-(3*5+14)*2-10 = 140 - (15+14)*2 - 10 = 140 - 29*2 - 10 = 140 - 58 - 10 = 140 - 68 = 72
