第二关 口算小火车
15+9 = 24 17+3 = 20 10+10= 20 16+9 = 25 14+9 = 25
25-3= 22 30-20= 10 35-4= 31 90-20= 70 32-2= 30 1
12+4 = 16 19+5 = 26 13+7 = 20 20+4 = 24 12+2 = 14 2
16 + 1 = 17 12 + 2 = 14 15+5 = 20 17+9 = 26 14+4= 18 3
13 + 1 = 14 2 + 14 = 16 1 + 5 = 6 6 + 2 = 8 7 + 1 = 8 4
2 + 2 = 4 4 + 1 = 5 3 + 2 = 5 2 + 6 = 8 7 + 1 = 8 5
5 + 1 = 6 3 + 3 = 6 4 + 2 = 6 3 + 1 = 4 2 + 3 = 5 6
3 + 2 = 5 4 + 1 = 5 1 + 3 = 4 2 + 4 = 6 6 + 2 = 8 7
