B) 43 - 6 x {10 - [6 x 8 : (14 - 80) - 5] x 3}=

C) 50-(6 x 8 + 2) + (3 x 7 + 9)=

Answer 1

a) 62-40÷(12-8)+7×2= 62-40÷4+14= 62-10+14= 52+14=66 b) 43-6×{10-[6×8÷6-5]×3}= 43-6×{10-[48÷6-5]×3}= 43-6×{10-[8-5]×3}= 43-6×{10-3×3}= 43-6×{10-9}= 43-6×1= 43-6=37 c) 50-(48+2)+(21+9)= 50-50+30= 0+30=30

Answer 2

A) 62-40:(12-8)+8
62-40:2+8
62-20+8
