Question

Am si eu 3 exercitii :
( 9×7-6:3)- (81-8×8)=
73-4×3+(53-24:8×6)=
( 14+8:8):5+5-(29-3:3):4=

Answer 1

(9x7-6:3)-(81-8x8)=
(63-2)-(81-64)=
61-17=44

73-4x3+(53-24:8x6)=
73-12+(53-3x6)=
73-12+(53-18)=
73-12+35=
61+35=96

(14+8:8):5+5-(29-3:3):4=
(14+1):5+5-(29-1):4=
15:5+5-28:4=
3+5-7=
8-7=1

Answer 2

(9x7-6:3)-(81-8x8)=
=(63-3)-(81-64)=
=60-17=
=43
73-4x3+(53-24:8x6)
=73-4x3+(53-3x6)
=73-4x3+(53-18)
=73-4x3+35
=73-12+35
=61+35
=96
(14+8:8):5+5-(29-3:3):4=
=(14+1):5+5-(29-1):4=
=15:5+5-28:4=
=3+5-7=
=8-7=
=1
