Answer 1

a) 8+5×[20+3×(2+4×6)-15]-3=
8+5×[20+3×(2+24)-15]-3=
8+5×(20+3×26-15)-3=
8+5×(20+78-15)-3=
8+5×(98-15)-3=
8+5×83-3=
8+415-3=
423-3=
420

b) [150+12×8-(14×2-40:4)]×10=
[150+12×8-(28-10)]×10=
(150+12×8-18)×10=
(150+96-18)×10=
(246-18)×10=
228×10=
2280

c) 5+5×[5+2×(5+25×1-24:4)]=
5+5×[5+2×(5+25-6)]=
5+5×[5+2×(30-6)]=
5+5×(5+2×24)=
5+5×(5+48)=
5+5×53=
5+265=
270
