三年級(jí)上冊(cè)脫式計(jì)算題128道親愛的小朋友們，脫式計(jì)算是我們數(shù)學(xué)學(xué)習(xí)中的重要一環(huán)，它能幫助我們更清晰地理解運(yùn)算的順序，培養(yǎng)我們細(xì)心計(jì)算的好習(xí)慣。通過勤加練習(xí)，相信大家一定能熟練掌握脫式計(jì)算的方法，讓計(jì)算變得又快又準(zhǔn)確！下面就是為大家準(zhǔn)備的128道脫式計(jì)算題，一起來挑戰(zhàn)吧！一、運(yùn)算順序要記牢在開始練習(xí)之前，我們先來回顧一下脫式計(jì)算的運(yùn)算順序，這可是做題的“金鑰匙”哦：1.只有加減或只有乘除：從左往右，依次計(jì)算。2.既有加減又有乘除：要先算乘除，后算加減。3.有小括號(hào)：要先算小括號(hào)里面的。記住這些規(guī)則，計(jì)算的時(shí)候才不會(huì)出錯(cuò)哦！二、脫式計(jì)算練習(xí)（一）只有加減的混合運(yùn)算1.25+18+36=______2.80-23-35=______3.37+45-29=______4.92-56+17=______5.19+68+11=______6.76-38-22=______7.53+29-41=______8.88-49+25=______9.33+47+15=______10.100-64-26=______11.28+57-39=______12.95-37+28=______13.44+36+12=______14.83-29-35=______15.59+21-48=______16.70-33+45=______17.22+69+8=______18.90-54-27=______19.48+32-55=______20.86-47+31=______21.35+55+7=______22.100-28-56=______23.51+39-44=______24.93-67+29=______25.29+43+28=______26.81-35-29=______27.46+27-38=______28.98-59+16=______29.31+59+10=______30.75-42-28=______（二）只有乘除的混合運(yùn)算31.3×6×4=______32.72÷8÷3=______33.8×4÷2=______34.45÷9×6=______35.5×7×2=______36.64÷8÷2=______37.9×3÷9=______38.24÷3×5=______39.4×8×2=______40.81÷9÷3=______41.6×6÷4=______42.36÷6×7=______43.7×2×5=______44.49÷7÷7=______45.8×9÷6=______46.54÷9×8=______47.3×8×3=______48.56÷7÷4=______49.10×4÷5=______50.27÷3×4=______51.6×5×2=______52.72÷9÷4=______53.8×8÷16=______54.30÷5×9=______55.2×9×4=______56.48÷6÷2=______57.5×6÷3=______58.63÷7×3=______59.4×7×2=______60.32÷4÷4=______（三）既有加減又有乘除的混合運(yùn)算61.20+3×6=______62.50-7×5=______63.4×8+15=______64.65-40÷5=______65.36+54÷9=______66.7×9-28=______67.80-6×8=______68.25+36÷6=______69.9×4+27=______70.63÷7+35=______71.5×7-19=______72.48÷8+42=______73.30+6×7=______74.72-8×8=______75.6×6+29=______76.90-54÷6=______77.28+4×9=______78.56-3×9=______79.8×3+46=______80.70-49÷7=______81.18+72÷8=______82.6×5-17=______83.40+9×3=______84.81-63÷9=______85.5×8+37=______86.64-8×5=______87.22+45÷9=______88.7×7-30=______89.35+6×4=______90.95-7×7=______91.4×5+56=______92.60-36÷4=______93.19+8×8=______94.7×6-22=______95.50+27÷3=______96.88-9×9=______（四）帶有小括號(hào)的混合運(yùn)算97.(15+25)÷5=______98.8×(12-7)=______99.(70-46)÷6=______100.36÷(3×3)=______101.(22+34)÷8=______102.9×(81÷9)=______103.(56-16)÷8=______104.4×(3+6)=______105.(30+24)÷9=______106.64÷(16-8)=______107.(45-27)×2=______108.7×(5+4)=______109.(63÷7)+28=______110.90-(18+29)=______111.(100-76)÷6=______112.5×(14-9)=______113.(28+42)÷7=______114.81÷(3×3)=______115.6×(7+2)=______116.(92-47)÷5=______117.35+(50-23)=______118.(4×7)-15=______119.72÷(8-2)=______120.(19+35)÷6=______121.8×(6+3)=______122.(76-68)×5=______123.49÷(21÷3)=______124.(36+27)-45=______125.6×(15-8)=______126.(80-52)÷4=______127.23+(4×8)=______128.90-(6×9)=______三、練習(xí)小貼士1.認(rèn)真讀題：看清數(shù)字和運(yùn)算符號(hào)，特別是有沒有小括號(hào)。2.確定順序：每做一步之前，先想一想這一步該
