加减乘除计算公式

加减法公式:(加数)+ (加数)=(

(a) + (b) ()+(b)= (a) + ():

=(c) = (c) =(c),



解:(a) = (c) ( b ) 解:(b ) = ( c ) ( a )o

乘法公式(乘数)X(乘数)=()



(a) X (b)= ()X(b)= (a) X ()=



(c) (C), (c),



解:(a ) = ( c ) ( b )

解:(b ) = ( c ) •? ( a )

除法公式:



1(被除数)(除数)=



()



(a) 4- (b) = (c)



()-(b) =(c)



:(a) = (c) X ( b )o

) = (c)

(a) 4- ( 解:(b ) = (a ) -r (c)

().... ・・・・・(余数)



2(被除数)(除数)=

(a) ~ (b)

= (c)ooooooo (h)

()-T- (b) = (c)ooooooo (h)解:(a)=(b) X(c) +(h)

(a ) 4- ( ) = (c)<»oooooo (h)解:(b)=[(a) (h) ] -r(c)

加减法混合算式:从前向后的顺序计算。a+b-c = d 乘除法混合算式:从前向后的顺序计算。aXb-rc = d 加减乘除混合算式:有括号先算括号里,没


有括号先算乘除,后算加减。
