回答1:

真的?

① -6÷(-3×2)
= -6 ÷ (-6)
= 1

② 17-8÷(-2)+4×(-3)
= 17 - (-4) + (-12)
= 17 + 4 - 12
= 9

③3^2-50÷(-2)^2×(+0.1)-1
= 9 - 50 ÷ 4 × 0.1 - 1
= 8 - 12.5 × 0.1
= 8 - 1.25
= 6.75

回答2:

3.76-[0.76+0.88] 0.32÷8÷0.2 0.63÷9÷4
=3.76-1.74 =0.04÷0.2 =0.07÷4
=0.0164 =0.2 =0.0175

说话算话,我想问一下你几年级?????

-6÷(-3×2)
=-6÷(-6)
=1

17-8÷(-2)+4×(-3)
=17-(-4)+(-12)
=9

3^2-50÷(-2)^2×(+0.1)-1
=9-50÷4×(0.1)-1
=9-1.25-1
=6.75

...这个...
