4322乘1233减4321乘1234怎么简算

4322乘1233减4321乘1234怎么简算
4322×1233-4321×1234
=(4321+1)×1233-4321×(1233+1)
=4321×1233+1×1233-4321×1233-4321×1
=1233-4321
=-3088

4322*1233-4321*1234
=（4321+1）*1233-4321*（1233+1）
=4321*1233+1233-4321*1233-4321
=1233-4321
=-3088

4322*1233-4321*1234
=(4321+1)*1233-4321*1234
=4321*1233+1233-4321*1234
=4321*1233-4321*1234+1233
=4321*(1233-1234)+1233
=4321*(-1)+1233
=1233-4321
=-3088

(4321+1)x1233 - 4321x(1233+1)

4322*1233-4321*1234
=4322*1233-4321*(1233+1)
=(4322*1233-4321*1233)-4321
=(4322-4321)*1233-4321
=1233-4321
=-3088
