一、口算:40%
470-180 = 320-60 = 2×4×5 = 91-35 =
330+160 = 59+21 = 10×8-8 = 60÷5 =
500-235 = 376+25 = 750-69 = 320×4 =
350+750 = 0÷90 = 430+80 = 84÷7 =
120×50 = 630÷70 = 7000-50 = 154+56 =
15×8 = 26×9 = 10000÷10 = 4000÷50 =
27×30 = 0×930 = 40+380 = 36×90 =
320-180 = 8000÷2 = 102+29 = 560÷4 =
125-25×2 = 501×6 = 75+25÷5= 48-0÷8 =
70×(60-52)= 45+55÷11 = 32÷4×12 = 360÷6+4 =
二、竖式计算:18%(打*的要验算)
* 991÷5 = 774÷6 = 109×7 =
926×6 = * 2450+3890 = *1060-109 =
递等式计算(能巧算的要巧算):24%
740×5×2 857-149-151 456-56÷8
99×7+7 600÷(96÷6-6) 435+298-135
