四年级脱式计算题500道

四年级脱式计算题500道亲爱的同学们，脱式计算是数学学习中的重要基础，它不仅能帮助我们熟练掌握运算顺序，还能培养清晰的解题思路和细致的计算习惯。扎实的脱式计算能力，就像盖房子时坚实的地基，能让我们在后续更复杂的数学学习中走得更稳、更远。这份500道脱式计算题，按照运算类型和难度梯度进行了编排，希望能为大家提供系统的练习。请同学们在练习时，务必严格按照运算规则，规范书写步骤，做到每一步都清晰明了。一、脱式计算运算规则回顾在开始练习之前，让我们一起回顾一下脱式计算的基本运算规则，这是确保计算正确的前提：1.同级运算（只有加减或只有乘除）：按照从左到右的顺序依次计算。2.不同级运算（既有加减又有乘除）：要先算乘除，后算加减。3.有括号的运算：要先算括号里面的，再算括号外面的。如果括号里既有乘除又有加减，同样遵循先乘除后加减的规则。4.书写规范：每一步计算的结果都要写在等号的后面，等号要上下对齐。暂时不算的数字和运算符号要照抄下来，不能遗漏。二、脱式计算题练习接下来，就让我们带着这些规则，开始今天的练习吧！请同学们认真对待每一道题，争取做到又快又准。（一）只有加减的两步运算1.56+23+172.89-35-243.72+18-454.90-54+365.33+47+126.100-62-287.45+38-198.67-29+539.28+55+1710.93-46-3711.51+39-2612.78-25+4113.36+44+1014.80-33-2715.59+21-3816.70-42+2917.22+68+918.95-58-2219.48+36-2720.63-35+4721.39+25+3122.87-49-2823.55+25-3624.76-38+2925.26+57+1326.91-55-2627.53+37-4428.69-31+5229.34+46+1530.85-42-3331.57+23-3932.74-28+3633.30+50+2034.99-63-2735.52+38-4136.71-33+4937.29+51+1638.88-45-3539.49+31-2240.65-27+5541.35+45+1542.92-56-2443.54+26-3844.77-39+2845.24+66+846.86-51-2947.50+30-2548.68-32+4449.37+23+3050.94-48-3651.58+22-4052.73-34+4753.32+48+1954.81-43-2855.46+34-2956.66-28+5257.27+53+1958.90-53-2759.50+40-3560.75-37+2861.31+49+1262.83-44-2663.47+33-2864.64-26+5165.25+65+1066.89-57-2367.53+27-3968.72-33+4669.38+42+1470.84-41-2971.56+24-3772.69-30+4573.23+67+1574.91-52-2875.44+36-2576.61-23+5877.30+50+1878.86-43-3779.52+28-3680.70-31+4981.26+54+1982.93-59-2183.49+31-2784.68-34+5285.33+47+1686.88-49-2187.55+25-3888.74-36+4289.29+51+1890.85-42-3391.48+32-2992.67-28+5193.34+46+1794.90-55-2595.51+29-3796.73-35+4897.24+66+1598.87-48-2299.45+35-26100.65-27+53101.36+44+13102.82-43-27103.57+23-38104.71-32+49105.28+52+19106.85-46-24107.43+37-28108.63-25+50109.32+48+14110.81-42-28111.54+26-39112.69-31+47113.23+67+16114.88-53-27115.49+31-26116.66-28+54117.35+45+12118.92-58-22119.50+40-36120.70-33+48121.29+51+13122.83-45-25123.47+33-29124.68-30+52125.37+43+15（二）只有乘除的两步运算1.8×3×22.72÷8÷33.6×9÷34.48÷6×55.5×7×26.90÷9÷27.4×8÷28.36÷4×79.3×6×410.64÷8÷411.7×5÷512.42÷7×613.9×2×514.81÷9÷315.6×8÷416.54÷6×417.2×9×318.72÷9÷419.5×6÷320.35÷5×821.4×4×522.63÷7÷323.8×7÷424.40÷8×925.3×8×326.56÷7÷227.9×4÷628.27÷3×629.5×5×430.48÷6÷431.7×6÷332.32÷4×533.6×3×334.60÷6÷535.8×9÷636.45÷9×737.2×8×438.54÷9÷239.4×9÷340.28÷4×641.3×7×342.70÷7÷543.9×5÷544.36÷6×845.5×8×246.49÷7÷747.6×7÷248.56÷8×349.4×6×250.54÷6÷351.8×5÷452.42÷6×553.3×9×254.63÷9÷755.7×8÷456.30÷5×957.2×7×558.48÷8÷359.9×6÷360.24÷3×761.5×4×362.72÷8÷963.6×6÷464.44÷4×2(注：此处44可改为40，更符合四年级初期，但44÷4=11也是整数，可保留)65.3×5×666.50÷5÷267.8×6÷368.36÷4×669.2×6×670.64÷8÷271.7×7÷772.21÷3×873.4×7×274.45÷9÷575.9×3÷976.56÷7×477.3×4×778.32÷8÷479.6×5÷280.49÷7×681.5×9×282.54÷9÷683.8×4÷284.35÷5×685.2×5×886.63÷7÷387.7×9÷388.28÷7×889.4×8×290.40÷5÷491.9×8÷692.33÷3×4(注：此处33可改为30)93.3×3×994.56÷8÷795.6×4÷896.48÷6×597.2×4×998.60÷6÷299.5×7÷7100.27÷9×8101.4×5×4102.54÷9÷3103.8×3÷4104.36÷3×2(注：此处36÷3=12)105.3×6×5106.42÷7÷6107.7×4÷2108.55÷5×3(注：此处55可改为50)109.2×8×3110.64÷8÷4111.9×5÷5112.30÷6×9113.5×3×7114.
