Verified answer

Answer:

1. 32÷2×2

= 32 ÷ 4

= 8

2. 6÷2+1×4

= 6÷2+4

= 3 + 4

= 7

3. [15-6]+[4-1]×[10-3]

= 9+3×7

= 9+21

= 30

4 .3×[3+2×[10-3]

= 3×(3+2×7)

= 3×(3+14)

= 3×17

= 51

5. [2+3×3{3[4+(9-8)-2]-3}

= [2+3×3{3[4+1-2]-3}

= [2+3×3{3[5-2]-3}

= [2+3×3{3[3]-3}

= [2+3×3{9-3}

= [2+3×3{7}

= [2+3×3{7}

= 2+3×21

= 2+63

= 65
