42×2 = 47+ 32= 1000克× 3 = 68+ 17=
80÷ 4= 42÷ 2 = 20分+ 30分= 500× 6=
60× 3= 72 -28= 4 ×22 = 84 -34=
66÷ 6= 55 +37= 43 ×2 = 44+ 46=
60÷ 2 = 52- 45 = 300 ×7 = 300+ 7=
65- 59= 66 +24 = 5× 800 = 44 ÷4 =
72 -8 = 3× 21 = 65- 35 = 1100-500=
4× 21 = 38 +19 = 4× 600 = 71- 24 =
80- 26= 82÷ 2 = 50- 26= 110× 8=
15+ 60= 75 -68= 66 ÷3 = 25+ 57=
46÷2 = 700+ 500 = 3×101 = 700 +900=
9 ×300= 1400 -800 = 36 ÷3 = 1300-600=
6 ×40 = 1200 -500 = 130× 3= 39+43 =
49-26= 93÷ 3 = 90-34= 2×210=
86÷2 = 31 + 36= 90-43= 800×8=
1200-400= 120- 40= 33× 2 = 25+32 =
3 + 26= 179 -79 = 2 ×14= 1400- 800=
