125 ×（17 × 8）× 4 375 × 480 + 6250 × 48
=125×8×4×17 =480×(375＋625)
=1000×68 =480000
=68000
25 × 16 ×125 13 × 99
=25×2×8×125 =13×(100－1)
=50000 =1300－13
=1287
75000 ÷ 125 ÷ 15 7900 ÷ 4 ÷ 25
=75×1000÷125÷15 =7900÷(4×25)
=75÷15×1000÷125 =79
=5×8
=40
150 × 40 ÷ 50 5600 ÷（25 × 7）
=150÷50×40 =56×100÷25÷7
=3×40 =56÷7×100÷25
=120 =32
210 ÷ 42 × 6 39600 ÷ 25
=210÷7÷6×6 =396×100÷25
=30 =396×4
