Third, judge right or wrong (right. Call, wrong number)

20 – 0 = 20 ( ) 5 + 15 = ( ) 10 + 5 = 10 ( )

18 +2 = 20( ) 7 +7 = 15( ) 10 + 10 = 18( )

20 - 10= 10( ) 10 – 0 =0( ) 6 + 14=20( )

7 + 13= 10( ) 4 – 1 =4( ) 2 + 3=5( )

Fourth, the columns are vertical.

5 + 44 = 22 + 77 = 50 + 49 =

46 – 3 = 7 + 62 = 88 – 44 =

Five, look at the diagram column formula

( ) + ( )=( ) ( ) + ( ) =( )

☆☆☆☆☆☆☆☆ + ☆☆☆☆=? + =?
