Răspuns :

Explicație pas cu pas:

a=20×25+50+4+10×10

a=500+50+4+100

a=550+4+100

a=554+100

a=654

b=10 000:100:10:5

b=100:10:5

b=10:5

b=2

a-b=?

654-2=652

a+b=?

654+2=656

a×b=?

654×2=1 308

a:b=?

654:2=327

a:100+b×5=?

654:100+2×5=6,54+10=16,54

(a+b)×10:2=

(654+2)×10:2=656×10:2=6 560:2=3 280
