一、直接写得数

÷= ÷9= ÷= 108÷= ÷= ÷= ×100= ×8= ÷= ×4= ×= ÷= ×= ×= ×= ÷=

352154 + 6 = 3 - 4 = 7- 7 = 58 + 111213 = 2 - 5 = 9 + 2 = 56 - 141736 = 7 - 3 = 8 - 4 = 47 -162316 = 7 - 3 = 10 +4 = 13 - 15 = 11516 +4 = 7 - 5 = 412 + 2

3 = 310 + 7

10 = 14 +3

8 = 37 + 1

9 = 310 + 1

10

=

713117121

- - = - - = 1- - = 10101066633

二、解方程x+ = x- = x- = 1

74

x-( 7135 - 5 ) = 5 12236 +3 + x = 24 12814 x+x = 3

4 x+56 x - 116x=4 6=

x- 111315 =30
