答案
解析:
这些题目主要考查了基础的数学运算能力,包括乘法、除法、加法和减法等基本算术运算。
答案:
$35 × 2 = 70$
$42 × 30 = 1260$
$480 ÷ 40 + 20 = 12 + 20 = 32$
$700 ÷ 35 = 20$
$420 ÷ 30 = 14$
$120 ÷ 40 + 70 = 3 + 70 = 73$
$700 ÷ 2 = 350$
$28 × 40 = 1120$
$80 + 120 ÷ 40 = 80 + 3 = 83$
$28 × 5 = 140$
$280 ÷ 40 = 7$
$70 × 80 - 3500 = 5600 - 3500 = 2100$
$140 ÷ 5 = 28$
$480 ÷ 80 = 6$
$50 × (240 ÷ 4) = 50 × 60 = 3000$
$140 ÷ 28 = 5$
$38 × 20 = 760$
$6 × 50 ÷ 30 = 300 ÷ 30 = 10$
$24 × 5 = 120$
$960 ÷ 40 = 24$
$60 × 5 - 60 = 300 - 60 = 240$
$120 ÷ 24 = 5$
$27 × 30 = 810$
$94 × 5 + 30 = 470 + 30 = 500$
$30 × 50 = 1500$
$560 ÷ 80 = 7$
$35 ÷ 7 × 70 = 5 × 70 = 350$
$1500 ÷ 30 = 50$
$507 × 7 = 3549$
$20 × (36 + 44) = 20 × 80 = 1600$
