13.6x5.8+3.6x4.4-0.72
=(10+3.6)x5.8+3.6x4.4-0.72
=10x5.8+3.6x5.8+3.6x4.4-0.72
=58+(3.6x5.8+3.6x4.4)-0.72
=58+3.6x(5.8+4.4)-0.72
=58+3.6x10.2-0.72
=58+3.6x(10+0.2)-0.72
=58+3.6x10+3.6x0.2-0.72
=58+36+(0.72-0.72)
=94+0
=94
=(10+3.6)x5.8+3.6x4.4-0.72
=10x5.8+3.6x5.8+3.6x4.4-0.72
=58+(3.6x5.8+3.6x4.4)-0.72
=58+3.6x(5.8+4.4)-0.72
=58+3.6x10.2-0.72
=58+3.6x(10+0.2)-0.72
=58+3.6x10+3.6x0.2-0.72
=58+36+(0.72-0.72)
=94+0
=94

13.6×5.8+3.6×4.4-0.72
=（10+3.6）×5.8+3.6×4.4-0.72
=10×5.8+3.6×5.8+3.6×4.4-0.72
=58+3.6×（5.8+4.4）-0.72
=58+3.6×10.2-0.72
=58+3.6×（10+0.2）-0.72
=58+36+0.72-0.72=94
=（10+3.6）×5.8+3.6×4.4-0.72
=10×5.8+3.6×5.8+3.6×4.4-0.72
=58+3.6×（5.8+4.4）-0.72
=58+3.6×10.2-0.72
=58+3.6×（10+0.2）-0.72
=58+36+0.72-0.72=94
