Question

9070*9-(5672+4098)=

8100:90*320-9087=

(1030-178):3*7=

8400:600*15+790=

Answer 1

9070*9-(5672+4098)=71860
5672+4098=9770
9070*9=81630
81630-9770=71860

8100:90*320-9087=19713
8100:90=90
90*320=28800
28800-9087=19713

(1030-178):3*7=1988
1030-178=852
852:3=284
284*7=1988

8400:600*15+790=1000
8400:600=14
14*15=210
210+790=1000
