In mathematics, binomial coefficients are represented as \(\binom{a}{b}\), where \(a\) is the \((a-1)^{\text{th}}\) row, and \(b\) is the \((b-1)^{\text{th}}\) number in that row, counting from the left, acting as an index.
Hockey is a team sport that incorporates balance, endurance, and hand-eye coordination. Choosing the proper hockey equipment is important to protect from injuries or dental damage. Hockey players need to drink plenty of water because the heat and weight of the equipment can cause dehydration.
An ice hockey stick is a piece of equipment used in ice hockey to shoot, pass, and carry the puck. Ice hockey sticks are approximately 150â200 cm long, composed of a long, slender shaft with a flat extension at one end called the blade. The blade is the part of the stick used to contact the puck, and is typically 25 to 40 cm long.
