Question

10- 3×3+4×2-5×1= 18-(4+1)×3-(4-3)×2+4= 17-(3+5)×2+2×(4-3)+3= 18-(3+5)×2+2×(8-4)+3= 5×2-3×3+4×2= (7-2)×3+5×(4-3)= Помогите решить.

Answer 1

(7-2)•3+5•(4-3)=5•3+5•1=15+5=20

Answer 2

10-3×3+4×2-5×1=10-9+8-5=4,
18-(4+1)×3-(4-3)×2+4=18-5×3-1×2+4=18-15-2+4=5,
17-(3+5)×2+2×(4-3)+3=17-8×2+2×1+3=17-16+2+3=6,
18-(3+5)×2+2×(8-4)+3=18-8×2+2×4+3=18-16+8+3=13,
5×2-3×3+4×2=10-9+8=9,
(7-2)×3+5×(4-3)=5×3+5×1=15+5=20
