小学二年级数学脱式计算题300道

小学二年级数学脱式计算题300道前言脱式计算，也叫递等式计算，是小学数学学习中的重要环节。它不仅能帮助孩子们巩固基本的加减乘除运算能力，更能培养他们清晰的解题思路和规范的书写习惯，为后续学习更复杂的混合运算打下坚实基础。对于小学二年级的同学而言，熟练掌握脱式计算的方法，按照运算顺序逐步计算，是提升数学素养的关键一步。本文精心编排了300道适合二年级学生的脱式计算题，希望能为孩子们的数学练习提供有益的帮助。二年级脱式计算基本运算规则回顾在开始练习之前，我们先来简单回顾一下二年级阶段脱式计算需要遵循的基本运算规则：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。例如：在计算只有加法和减法的算式时，先算左边的，再算右边的；计算只有乘法和除法的算式时，同样从左往右依次进行。2.含两级运算（既有加减又有乘除）：要先算乘除法，后算加减法。这是非常重要的规则，需要牢记。在书写脱式计算时，要注意等号必须写在算式的左边，并且上下对齐，每一步计算的结果写在等号后面。脱式计算题练习一、同级运算（只有加减或只有乘除）（一）只有加减运算1.15+6+202.30-8-123.25+18-94.42-15+75.8+27+156.50-16-247.19+33-218.63-29+179.12+48+2010.70-25-3511.36+14+2512.85-30-2713.22+56-3814.90-45+1515.17+28+3516.66-22-1817.31+19-2618.75-33+2819.9+36+4520.100-50-3021.29+41+1022.60-18-2223.44+26-3524.88-40+1225.13+37+2526.72-28-2227.26+48-3928.95-59+1429.5+45+3030.68-19-2131.38+22+1532.80-36-2433.49+11-3034.55-27+3335.20+50+2536.92-46-3437.16+64-4038.74-23+1639.21+29+3040.65-35-2041.33+33+1442.100-60-2543.47+13-2044.58-28+3245.10+60+2946.76-32-2847.28+52-4548.83-43+1749.14+46+3050.90-55-2551.35+25+1852.64-17-2353.51+19-3654.77-38+2155.22+38+1056.81-29-3157.18+42+2558.69-39+2159.9+51+3060.50-15-2561.40+20+3062.88-44-2663.29+31-1564.73-27+1365.16+24+4566.95-45-3067.37+23-1968.50-20+3569.8+42+3570.80-30-2571.43+17+2072.66-26-3073.25+55-4074.92-52+1875.19+31+25（二）只有乘除运算76.3×4×577.6×2×778.81÷9÷379.24÷3÷280.5×2×681.9×1×882.48÷6÷483.36÷4÷384.2×5×485.7×3×286.64÷8÷287.42÷7÷388.4×6×289.8×2×390.72÷8÷391.54÷9÷292.3×3×793.5×8×194.30÷5÷395.28÷4÷796.6×5×297.4×4×498.90÷9÷599.32÷8÷2100.7×2×5101.3×6×3102.63÷7÷3103.40÷5÷4104.5×5×2105.2×9×3106.45÷9÷1107.56÷7÷4108.8×3×2109.6×6×1110.27÷3÷3111.60÷6÷5112.9×2×4113.5×7×2114.36÷6÷2115.49÷7÷7116.4×5×3117.3×8×2118.54÷6÷3119.25÷5÷5120.2×2×9121.7×4×2122.80÷8÷5123.30÷3÷5124.6×3×3125.8×5×1二、含两级运算（先算乘除，后算加减）（一）先算乘法，后算加减126.5×3+15127.20+4×6128.6×7-20129.45-3×9130.8×2+30131.50+7×4132.9×5-35133.60-5×8134.3×6+22135.18+2×8136.4×9-17137.70-6×6138.7×3+29139.33+5×5140.8×6-30141.55-4×7142.2×9+40143.25+3×7144.10×4-15145.80-8×5146.6×4+18147.40+9×2148.7×7-25149.36-2×6150.5×8+12151.16+6×3152.3×10-20153.65-7×5154.9×3+21155.30+4×8156.5×5-10157.90-9×9158.2×7+56159.42+8×3160.6×8-32161.49-3×3162.4×4+36163.28+5×6164.10×3-12165.77-6×7166.8×4+14167.5+9×5168.7×8-40169.63-4×4170.3×8+26171.35+2×9172.5×9-25173.50-3×8174.6×2+48175.19+7×7176.8×9-45177.40-5×5178.9×4+16179.22+10×2180.3×7-11181.88-8×6182.5×6+34183.44+4×4184.9×6-39185.75-5×5186.2×8+50187.31+3×3188.6×9-27189.60-2×7190.4×7+22191.53+6×2192.8×3-14193.99-9×5194.7×5+15195.20+8×8（二）先算除法，后算加减196.18÷3+12197.25+30÷5198.40÷8-2199.36-14÷2200.24÷4+18201.40+56÷7202.63÷9-5203.50-27÷3204.35÷5+20205.16+28÷4206.49÷7-3207.60-36÷6208.12÷6+35209.54+45÷9210.56÷8-4211.70-40÷5212.30÷5+42213.21+18÷3214.32÷4-5215.80-54÷6216.42÷7+28217.33+24÷6218.64÷8-6219.45-16÷4220.27÷3+30221.19+36÷9222.72÷9-6223.55-25÷5224.8÷2+50225.60+14÷7226.48÷6-5227.90-72÷8228.15÷3+45229.28+63÷7230.36÷4-7231.66-12÷2232.56÷7+19233.44+30÷5234.20÷5-2235.75-35÷7236.36÷9+25237.50+8÷2238.40÷5-3239.58-24÷
