一、口算。

22+28+21= 81-32-18= 21+19-8= 39+36-66= 65-39+26= 28+28+28= 34+47-15= 91-19-56= 33+27+18= 15+55-33= 89-39-26= 12+18+37= 29+28+27= 51-16+26= 28+18-27= 89-19-28= 100-17-38= 18+49+28= 22+49-22= 21-8+39= 66-27+19= 38+14+19= 29+27+26= 37-29+16= 45+55-22= 100-65=26= 100-39-45= 24+47-26= 88-66+49= 28+19+17= 56+26-39= 67+27-45= 51-22+39= 73-37+38= 29+36-29= 30-13+68= 100-87+48= 66-39+47= 25-18+37= 100-55+45= 23+47-28= 100-28-35= 28+24-16= 42+8-19= 19+19+24= 34-8-17= 77-46+32= 65-38+26= 79+19-56= 58-36+27= 84-27+16= 4+27-16= 93+23+94= 69-(39-23)= 99+(25-24)= 77-76+32= 61-38+26= 79+19-16= 18-36+27= 87-27+16= 30+(23-29)= 73-23-4= 93-(39-23)= 71-(25-24)= 99-46+32= 65-39+26= 99+99-56= 59-36+29= 94-29+96= 30-(23-29)= 93-23+94= 33-(39-23)= 99-(25-24)= 99-96+32= 69-39+26= 99+99-96= 99-36+29= 99-29+96= 30-(23+29)= 23+23+94= 93-(39-23)= 9-(99-29)= 55-46+22= 65-28+26= 58+18-56= 58-26+25= 84-25+16= 24+25-16= 82+22+84= 68-(28-22)= 88+(25-24) = 55-56+22= 61-28+26= 58+18-16 18-26+25=

二、脱式计算。
