Question

Indică prin paranteze ordinea efectuării operațiilor și apoi calculează:63–24×2, 8×29–98, 550–73×7, 30×10–27×7, 18×6–14×5, 7×29–32×6, 36:6×47–199, 78–64:8–59, 78+32:4×65​

Answer 1

Răspuns:

63-24×2=63-(24×2)=63-48=15

8×29-98=(8×29)-98=232-98=134

550-73×7=550-(73×7)=550-511=39

30×10-27×7=(30×10)-(27×7)=300-189=111

18×6-14×5=(18×6)-(14×5)=108-70=38

7×29-32×6=(7×29)-(32×6)=203-192=11

36:6×47-199=(36:6×47)-199=(6×47)-199=282-199=83

78-64:8-59=78-(64:8)-59=78-8-59=70-59=11

78+32:4×65=78+(32:4×65)=78+(8×65)=78+520=598
