概要:320×3 = 4× 70 = 65 +35= 4 × 120=55+37= 4 ×12 = 38-19= 1400+1400=25×4 = 30 + 700 = 73-30 = 48÷ 4=二、多做多加分:33+( )=100 40÷ ( ) =20 60÷8 = 3×( )=30002×99+2= 180×2×0= 52 ÷ 4 = 30×3+ 4=80÷5÷4 = 1

55+37= 4 ×12 = 38-19= 1400+1400=
25×4 = 30 + 700 = 73-30 = 48÷ 4=
二、多做多加分:
33+( )=100 40÷ ( ) =20 60÷8 = 3×( )=3000
2×99+2= 180×2×0= 52 ÷ 4 = 30×3+ 4=
80÷5÷4 = 18-6-6-6= 75 ÷3= 98+17+2=
30+15+30+15= 84-7-3= 100×3×3= 20×4 ÷4=
12+12+12+12= 200×3×2 = 11×2×5= 504×8=
