简便运算36*1.28+8.2*3.6-3.6
简便运算36*1.28+8.2*3.6-3.6
简便运算36*1.28+8.2*3.6-3.6
36x1.28+8.2x3.6-3.6
=36x1.28+(8.2-1)x3.6
=3.6x12.8+7.2x3.6
=(12.8+7.2)x3.6
=20x3.6
=72
72
36×1.28+8.2×3.6-3.6
=3.6×12.8+8.2×3.6-3.6
=3.6×（12.8+8.2）-3.6
=3.6×21-3.6
=3.6×20
=72
36×1.28+8.2×3.6-3.6
=3.6×12.8+8.2×3.6-3.6
=3.6×（12.8+8.2）-3.6
=3.6×21-3.6
=3.6×20
=72
