Question

afla difernta dintre a si b stiind. a=73-27:(37-28)+2
b=(5+5x9):5x9

Answer 1

a=73-27:9+2
a=73-3+2
a=72

b=(5+45):5*9
b=50:5*9
b=10*9
b=90

a-b= 72-90= -18 Pentru ca tu esti in clasele primare, aceasta scadere nu se poate.

Answer 2

a=73-27:(37-28)+2=
=73-27:9+2=
=73-3+2=
=70+2=
=72
b=(5+5x9):5x9=
=(5+45):5x9=
=50:5x9=
=10x9=
=90

a-b=72-90=-18
