Truyện kể về một cô bé nghèo khổ, đi bán diêm vào đêm giao thừa, trong cái lạnh buốt giá của mùa đông. Cô bé không dám về nhà vì sợ bị bố mắng, nhưng cũng không bán được diêm cho ai. Trong lúc cô ngồi co ro, cô thắp từng que diêm để sưởi ấm mình và trong ánh sáng của mỗi que diêm, cô mơ thấy những hình ảnh ấm áp, hạnh phúc: lò sưởi ấm áp, bữa cơm ngon, cây thông và hình ảnh bà ngoại yêu thương. Cuối cùng, cô bé chết rét ngoài phố, nhưng trong cái chết, cô được gặp lại bà ngoại và được sống trong hạnh phúc vĩnh viễn.

=>Ý nghĩa chính: Truyện phản ánh nỗi bất hạnh, cô đơn của trẻ em nghèo trong xã hội, đồng thời khơi gợi lòng nhân ái, sự sẻ chia của con người với nhau.

\(30\% \cdot x - 0,5 = -2,75\)

\(0,3 \cdot x - 0,5 = -2,75\)

\(0,3 \cdot x = -2,75 + 0,5\)

\(0,3 \cdot x = -2,25\)

\(x = -2,25 : 0,3\)

\(x = -7,5\)

-7,5

1÷3-2÷33+1÷(-4)×2÷(-33)+(-1÷12)×(-2÷33)

A = 1/3.-2/33 + 1/-4.2/-33 + -1/12.-2/33

A = - 2/33.(1/3 - 1/4 - 1/12)

A = -2/33.(4/12 - 3/12 -1/12)

A = -2/23.(1/12 - 1/12)

A = -2/23.0

A = 0
