=7.8*5.6+2.3*(10-5.6) =7.8*(10-4.4)+2.3*4.4
=(7.8-2.3)*5.6+2.3*10 =78-(7.8-2.3)*4.4
=5.5*5.6+23 =78-5.5*4.4
=30.8+23 =78-24.2
=53.8 =53.8
=(7.8-2.3)*5.6+2.3*10 =78-(7.8-2.3)*4.4
=5.5*5.6+23 =78-5.5*4.4
=30.8+23 =78-24.2
=53.8 =53.8

7.8×5.6+2.3×4.4
=(10-2.2)×5.6+2.3×(2.2×2)
=56-2.2×5.6+2.2×4.6
=56-2.2×(5.6-4.6)
=56-2.2
=53.8
=(10-2.2)×5.6+2.3×(2.2×2)
=56-2.2×5.6+2.2×4.6
=56-2.2×(5.6-4.6)
=56-2.2
=53.8
