四年级下学期数学加减乘除混合运算300道

四年级下学期数学加减乘除混合运算300道同学们，四年级下学期的数学学习中，加减乘除混合运算是非常重要的一个环节。它不仅考验我们对单个运算的掌握程度，更考验我们对运算顺序的理解和运用能力。熟练掌握混合运算，能让我们的计算变得更有条理，也为后续学习更复杂的数学知识打下坚实的基础。下面，我们就通过大量的练习来巩固这部分知识吧！运算顺序要牢记：1.同级运算：从左往右依次计算（只有加减，或只有乘除）。2.不同级运算：先算乘除，后算加减。3.有括号的运算：要先算括号里面的。请同学们认真计算以下各题，注意书写工整，步骤清晰哦！一、基础热身（15道）1.25+75-302.100-45+553.36×2÷64.72÷8×35.15+25×26.80-12×57.30÷5+208.40-24÷39.6×8-1710.45+36÷911.70-20+3012.24÷4×513.9×3+2714.60÷6-815.50+50÷10二、进阶练习（两步运算，100道）16.18+2×917.54-36÷418.7×6+2819.90-6×720.42÷7+3521.5×8-2622.63+45÷923.81-18÷224.12×3+4825.75-5×926.20+64÷827.33-30÷628.8×7-3629.56+24÷330.99-9×931.40÷8+5332.6×9+2233.88-40÷534.27÷3+6535.10×4-1836.38+4×737.92-63÷738.5×5+4539.70-8×640.48÷6+2941.9×4-2042.61+35÷543.80-21÷344.14×2+5245.66-3×946.29+56÷747.50-36÷648.7×7+1549.85-10×550.36÷4+4451.6×8+3052.94-42÷753.25÷5+6054.8×3-1455.57+21÷356.76-8×857.49÷7+3358.9×5-2559.32+40÷860.68-18÷961.10+9×662.83-35÷563.42÷6+5864.6×6-1665.28+16÷466.77-21÷367.8×9+1268.90-54÷669.55+30÷670.7×4-1771.44-4×972.30÷3+4073.5×7+2374.81-63÷975.18÷2+6676.9×2+5677.60-24÷478.35+49÷779.8×4-2080.54-9×581.21+63÷782.70-30÷583.6×3+5084.48÷8+3285.95-7×786.16+8×587.63-48÷688.24÷3+5189.9×6-3090.40+28÷491.72-12×392.5×9+1593.33÷3+2294.80-8×495.22+36÷696.69-45÷997.7×3+4998.56÷7+2899.96-10×6100.19+25×2101.88-64÷8102.36×2-50103.45÷5+38104.6×10-25105.50+42÷7三、提升练习（含括号运算，100道）106.(15+25)×2107.80-(12+28)108.30÷(5+1)109.(40-16)÷3110.6×(8-3)111.(45+36)÷9112.70-(20×3)113.24÷(4+2)114.9×(3+3)115.(60-30)÷6116.(18+27)÷5117.54-(36-18)118.7×(6+2)119.90÷(6+3)120.(42+14)÷7121.5×(8+7)122.63÷(9-2)123.81-(18+27)124.(12+18)×4125.75-(5×9)126.(20+40)÷6127.40÷(8-3)128.8×(7-4)129.(56-24)÷4130.99÷(9+2)131.(40+50)÷10132.70-(20+25)133.24÷(4×2)134.(9×3)+27135.60÷(6+4)136.(50-10)÷8137.6×(8+12)138.94-(42÷7)139.(25+35)÷5140.8×(3+5)141.57-(21+18)142.(76-36)÷8143.49÷(7+0)144.9×(5-2)145(32+48)÷10146.68-(18÷9)147.(10+20)×3148.83-(35+15)149.42÷(6+1)150.(6×6)-16151.(28-16)÷4152.77-(21+35)153.8×(9-5)154.(90-54)÷6155.55+(30÷6)156.(7+4)×7157.44-(4×9)158.(30+30)÷3159.5×(7+6)160.81-(63÷7)161.(18+6)÷2162.9×(2+6)163.60-(24+16)164.(35+49)÷7165.8×(4+5)166.54-(9×5)167.(21+63)÷7168.70÷(30÷6)169.6×(3+7)170.(48+32)÷8171.95-(7×7)172.(16+24)×2173.63-(48÷8)174.24÷(3×2)175.9×(6+4)176.(40-28)÷4177.72-(12×3)178.(5×9)+15179.33÷(3+8)180.80-(8×8)181.(22+34)÷6182.69-(45÷9)183.7×(3+7)184.(56+28)÷7185.96-(10×6)186.(19+25)÷6187.88-(64÷4)188.(36+24)×2189.45÷(5+4)190.6×(10-5)191.(50-14)÷6192.70-(42÷7)193.(15+35)×2194.30÷(5-2)195.8×(8-3)196.(60-36)÷4197.55-(25÷5)198.(10+9)×3199.83-(35+20)200.(42-12)÷6201.6×(8+5)202.(45+15)÷5203.70-(20+20)204.24÷(4+4)205.(9+3)×5四、综合挑战（三步及以上运算，75道）206.15+25×2-30207.100-(45+55÷5)208.36×(2+6)÷8209.72÷(8-5)×3210.15+(25-10)×2211.80-12×5+15212.30÷5+20×3213.40-(24÷3+10)214.6×8-17+23215.45+36÷9×2216.70-20+30×2217.24÷4×5-18218.9×3+27÷9219.60÷(6+3)-8220.50+50÷10×4221.(18+2)×(9-4)222.54-36÷(4+2)223.7×6+28÷7224.90-6×(7-2)225.42÷7+35-15226.5×(8-3)+26227.63+(45÷9+11)228.81-18÷2×3229.12×3+48÷12230.75-5×9+20231.20+64÷(8-4)232.33-(30÷6+10)233.8×7-36+202
