三年级上册脱式计算题128道

三年级上册脱式计算题128道亲爱的小朋友们，脱式计算是我们数学学习中的重要一环，它能帮助我们更清晰地理解运算的顺序，培养我们细心计算的好习惯。通过勤加练习，相信大家一定能熟练掌握脱式计算的方法，让计算变得又快又准确！下面就是为大家准备的128道脱式计算题，一起来挑战吧！一、运算顺序要记牢在开始练习之前，我们先来回顾一下脱式计算的运算顺序，这可是做题的“金钥匙”哦：1.只有加减或只有乘除：从左往右，依次计算。2.既有加减又有乘除：要先算乘除，后算加减。3.有小括号：要先算小括号里面的。记住这些规则，计算的时候才不会出错哦！二、脱式计算练习（一）只有加减的混合运算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）只有乘除的混合运算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）既有加减又有乘除的混合运算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）带有小括号的混合运算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、练习小贴士1.认真读题：看清数字和运算符号，特别是有没有小括号。2.确定顺序：每做一步之前，先想一想这一步该
