Va rogggggggg : 2+3+.........+100
Urgenttt

Answer 1

Poti aduna un 1 la inceput si sa-l scazi la sfarsit pt. a obtine suma Gauss:
2+3+...+100=1+2+3+...+100-1=100x101:2-1=5050-1=5049

Answer 2

Gauss

1 + 2 + ... + n = n(n + 1) : 2

S = (1 + 2 + ... + 100) - 1

S = 100·101 : 2 - 1

S = 5050 - 1

S = 5049
