16×35÷8

这样的计算,先选择方便计算的先后顺序,这样容易简算。 16*35/8,可以调整计算顺序: (16/8 )*35 =2*35 =70

35/56 =5×7/7×8 =5/8 =0.625

(75-35)×8÷16 =40x8÷8÷2 =40÷2 =20 祝学习进步。

(4-4÷16/5)×2/5 =(4-4x5/16)x2/5 =(4-5/4)x2/5 =11/4x2/5 =11/10 35÷7/8×2-2/7 =35x8/7x2-2/7 =40x2-2/7 =80-2/7 =79又5/7 4.5×8×1.25÷4.5 =(4.5÷4.5)x(8x1.25) =1x10 =10

(900-16×35)÷34怎么计算 =(900-560)÷34 =340÷34 =10
