Question

Calculeaza in doua moduri a)(245+329)×2;;;b) 5×(63-12)=

Answer 1

a) (245+329)×2=
=574×2=
=1148
Sau fara paranteze:
245+329×2= (calculam mai intai inmultirea)
=245+658=
=203

Asa procedezi si la:

b) 5×(63-12)=
=5×51=
=255

Sau fara paranteze:

5×63-12= (am calculat prima data inmultirea)
=315-12=
303
