(1)352-98, =352-100+2, =252+2, =254; (2)725+363+75, =725+75+363, =800+363, =1163; (3)306-197, =306-200+3, =106+3, =109; (4)970-346-154, =970-(346+154), =970-500, =470.

1.3500除以五百简便计算 3500÷500 =(3500÷500)÷(500÷500) =7÷1 =7

500除以36简便计算 500除以36 =500÷4÷9 =125÷9 =125/9

500÷25×4用简便运算 500÷25×4 =5*100/25*4 =5*4*4 =20*4 =80

32乘(500-50)用简便方法计算 32*(500-50) =32*500-32*50 =16000-1600 =14400
