①-6÷(-3×2)
②17-8÷(-2)+4×(-3)
③3^2-50÷(-2)^2×(+0.1)-1
我会给一定的分的,放心

-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...

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?????

真的?① -6÷(-3×2)= -6 ÷ (-6)= 1② 17-8÷(-2)+4×(-3)= 17 - (-4) + (-12)= 17 + 4 - 12= 9③3^2-50÷(-2)^2×(+0.1)-1= 9 - 50 ÷ 4 × 0.1 - 1= 8 - 12.5 × 0.1= 8 - 1.25= 6.75
