  2. 350减去240,差是多少? 270乘3,积是多少? 72与28的和是多少? 75除以15的商是多少? 列出算式并口算结果 350-240= 110 270×3= 840 72+28= 100 75÷15= 5

  3. 先说出运算顺序,再口算出结果 • 8+2×3 = • 45-(3+7)= • (26-14)÷6= • 18 ÷9×3= 14 35 2 6

  4. 练一练 • 1、90乘90的积减去90,差是多少? • 2、90加上90的和除以90,商是多少? 90×90-90 =810-90 =720 (90+90)÷90 =180÷90 =2

  5. 选择正确的答案 • (1)75加上25乘以3的积,和是多少? • A 75+25 ×3 B (75+25) ×3 • (2)75加上25的和,再乘以3的积是多少? • A 75+25 ×3 B (75+25) ×3 • C 75+(25 ×3 ) √ √

  6. (3)400除以25减去21的差,商是多少? • A 400÷25-21 B 400÷(25-21) • (4)400加上25减去21的差,和是多少? • A 400+25-21 B 400+(25-21) √ √

  7. 用文字描述下列算式 • (1) (1974+3684)÷(84-38) • (2)87×136+7144÷47 • (3)729×72÷(241-187)
