42*89-90=
32+90*89=
32*2-89=
278-89+80*2=
800-70+68*6=
29+797-209*7=
890-(80-89*8+90)-89=
898*2-((89*90-90)+90*2-92)+897=
(6756+22)*6-8+2667+28=
6867-(26+79)*6*(2*90+87)-57=
(7289-5266+662)*6*2-80+(667-222+682)*62=
27892-(26678+72*62-25)+2-6876+2*56=
2826-2892+278*27+829=
2782-27*62+(89-25)*27=
2728+(27-28+527)*67-72+28=
897-89-(72+781*87-771+7)*63=
72-282*78+9829-898=
89+728*(78-80+622-7)*7=
28276-2892+87*62-27+782=
运算量会不会有点大？

Answer 2
