Answer 1

801-46×7+90:3×9=

801-322+30×9=

479+270=749

4082+3579-25×4:10=

7.661-100:10=

7.661-10=7.651

84:4+84×26-42:6=

21+2.184-7=

2.205-7=2.198

45:5×73-11×38+45=

9×73-418+45=

657-418+45=

239+45=284

5067+10×3:5-42×31=

5067+30:5-1.302=

5067+6-1.302=

5073-1.302=3.771

67×100+63:9-52×7=

6700+7-364=

6.707-364=6.343
