41+42+43+44-21-22-23-24
=( 41- 21 )+ (42-22)+(43-23)+(44-24)
=20 + 20 +20 +20
=20 . 4
=80
41+ 42 + 43 + 44 - 21 - 22 - 23 - 24 = 80
41 + 42 + 43 + 44 - 21 - 22 - 23 - 24
= ( 41 - 21 ) + ( 42 - 22 ) + ( 43 - 23 ) + ( 44 - 24 )
= 20 + 20 + 20 + 20
= 80
41+ 42 + 43 + 44 - 21 - 22 - 23 - 24
=(41-21)+(42-22)+(43-23)+(44-24)
= 30 + 30 + 30 + 30
=30x4
=120
