E) 3. {43 – [5. 60 + 7. (92 – 80)]} =

Answer 1

A) 35 + 52 → +87

B) – 18 + 102 → +84

C) ( -3)2 + 50 + 165

-6 + 215

+209

D) 480: {20. [86 - 12. (5 + 2)] 2} =

480: {20. [86 - 12.7].2}

480: {20. [86 - 84].2}

480: {20.2.2}

480 : 80

6

E) 3. {43 – [5. 60 + 7. (92 – 80)]} =

3. {43 – [5. 60 + 7. 8]}

3. {43 – [300 + 56]}

3. {43 – 356}

3 . {-313}

-939
