21 955 = 20 000 , 21960

b)
59*(47+83)+800-79*(3800-3703) = 59*130+800-79*97 = 7 670+800-7 663= 807
807 = 810

Answer 2

5). 
a) 255+600x37-45x201+400=13810
=255+22200-9045+400=
=22455-9045+400=
=13410+400=
=13810
1310 rotunjit la zeci este 1310

b) 59x(47+83)+800-79x(3800-3703)=807
=59x130+800-79x97=
=7670+800-7663=
=8470-7663=
=807
807 rotunjit la zeci este 810
