Answer 1

6-{7-（5-2} =6-{7-5+2}
=6-7+5-2
=2

14-2{9-2（5-3）}
=14-2{9-10+6}
=14-2*5
=4

（2^3+1 ）/（2^2-1 ）
= 9/3
=3

3^2/ [5-(3-1)]
=3^2/3
=3

-(1|1+7^2 |) /(3| 5^2 |)
=-1*15/3*25
=-1/5

[2^2*(3^2+4^2)]/ 10^2
=[2*(9+16)]*100
= [2*25]/100
=1/2

64÷4^2+3(3^2-1)
=64÷16+3*(9-1)
=4+3*8
=28

2^2*3^2-(5^2-4^2)
=4+9-(25-16)
=4+9-9
=4

{3^3-(2^3+2^2)}÷5
={27-(8+4)}÷5
=15÷5
=3

1 - {2(3+4)-3^2} *10
=1-{2*7-9}*10
=1-5*10
=-49
