Answer 1

Explicație pas cu pas:

I

(220÷4+6)×100-[25+(299-77×3) 1+12=

(55+6)×100-[25+(299-231) ×1+12=

61×100-(25+68)×1+12=

6100-93×1+12=

6100-93+11=

6007+11=

6018

II

[700-(595-135×2-38×3)×2]-100=

[700-(595-270-114)×2]-100=

[700-(325-114)×2]-100=

(700-211×2)-100=

(700-422)-100=

278-100=

178

III

32×518×200-[775÷25×(172-85)]=

16576×200-(31×87)=

3315200-2697=

3312503

IV

(24×8000-190000):1000×63-36):45=

(192000-190000):1000×63-36):45=

(2000÷1000×63-36):45=

(2×63-36)÷45=

(126-36)÷45=

90÷45=
