四年级小数脱式简算40道
要简算!要有小数!要脱式!
要简算!要有小数!要脱式!
小学毕业好多年了,是不是8+5*（7+6）=这样的?
再问： 要小数的小数像1.1这样的带小数点的叫小数
再答： 8.5+(3.4+6.6)=这样吗？
再问： 嗯
再答： 2.1+(3.7+4.2)+(5.4+3.5)= 3.4+[3.7-(2.1+1)]= 1.6+3*2+(5-2)= 2.2-(3*2-4.1)= (19.7+2)*10= 4.5+(6+10-17.5)= 32.73+(9-6)+(0.9-0.6)= 6.6-(5.5-4.5)+(7.5-6)= 4.95+(6.7+3.3)= 0.63+18.9+2.37+5.91= 0.1+0.2+0.3+0.4+.....+0.9= 40-13.64-5.86= 18.86-3.47-0.53= 7.8+0.2-7.8+0.2= 23.4-0.8-13.4-7.2= 16.13+8.92-6.13= 4.25-0.83+0.75-1.17= 5.93+0.16+2.81= 1.806-(0.41+0.806)= (1.56+394)+(3.44+106)= 84.64-54.8-25.2= 2-0.87-0.13-0.12= 48.6-(8.6-1.28)= 4.02-3.5+0.98= 4.9+0.1-4.9+0.1= 6.7+4.95+3.3= (1.38+1.75)+0.25= 3.35+4.78+3.65= 2.74+0.83+1.17+0.26= 2.5+3.2-(0.8-0.72)= 0.24+0.75-(9.8-6.8)= 0.52+1.2+0.79-0.6= 0.608+9.72-8.84+0.905= 9.72-8.84+12.46-5.87= 0.1+0.2+0.3+7.9= 19.89-(5.73-4.27)= 42.54-(25.4+10.03)= 12.08-(2.08-1.49)= (2.84-1.06)+1.6= 125*(10+8)= 呼~不容易啊~~~~(>_
