小学二年级数学题970一290脱式计算怎么做 =(900+70)-(300-10) =(900-300)+(70+10) =600+80 =680

把计算过程完整写出来的运算,也就是脱离竖式的计算。在计算混合运算时,通常是一步计算一个算式(逐步计算,等号不能写在原式上),要写出每一步的过程。 例如:250÷50+12×4 =5+48 =53

970一290 =970-300+10 =(970-300)+10 =670+10 =680 朋友,请【采纳答案】,您的采纳是我答题的动力,谢谢。

2、脱式计算 24+12÷6 35-63÷7 5×8-39 (23+49)÷8 48-18÷3 (52-45)×6 23+5×8 2×6+37 90-3×9 8×7-34 7×5+18 32÷4+25 72÷(24-16) (34+47)÷9 56-2×6

200÷20×30 = = 85+14×20 = = 95÷(65-56) = = 120+36×4 = = 32×97 = = 85×91÷7 = = 67×(2×3) = = 43+943÷6 = = 91×3+149 = = 93×6+124 = = 324÷7+635 = = 44×30÷3 = = 221+22×4 = = 481×6×0 = = 384×6×7 = = 40÷2×174 = = 147+72÷8 = = 9×(9...

二年级下册的数学的脱式计算应用题 小聪去超市买薯条,每袋2元,买6袋。如果小聪给营业员20元,应找回 多少元? 解: 20-2×6 =20-12 =8 答:应找回 8元.

最佳答案77-46+32 65-38+26 79+19-56 56+74-26 = = = = = = = = 58-36+27 84-27+16= 4+27-16 = = = = = = 93+23+94 69-(39-23) 99+(25-24) = = = = = = 77-76+32 61-38+26 79+19-16 16+77-26 = = = = = = = = 18-36+27 87-27+16 30+(23-29) = ...

1+2+3+4 = 3+3+4 = 6+4 = 10
