如题所述
计算过程:
=11x22+0.22x100x33+4.4x5x66
=11x22+22x33+22x66
=22x(11+33+66)
=22x(100+10)
=2200+220
=2420
=11x22+0.22x100x33+4.4x5x66
=11x22+22x33+22x66
=22x(11+33+66)
=22x(100+10)
=2200+220
=2420

先把4.4转换为2×2.2,再把11×22转换为110×2.2,把0.22×3300转换为2.2×330,用分配律计算。
11×22+0.22×3300+330×4.4
=11×22+0.22×3300+330×2×2.2
=110×2.2+2.2×330+660×2.2
=2.2×(110+330+660)
=2.2×1100

11×22+0.22×3300+330×4.4
=11×22+0.22×3300+330×2×2.2
=110×2.2+2.2×330+660×2.2
=2.2×(110+330+660)
