Math question: What is the sum of the squares of the digits of the number 1658?

To find the answer, we need to square each digit in the number 1658, then sum them up. The digit 1 squared is 1, digit 6 squared is 36, digit 5 squared is 25, and digit 8 squared is 64. Adding those values together: 1 + 36 + 25 + 64 = 126. Hence, the sum of the squares of the digits of 1658 is 126.

Math Question: What is the sum of the digits of the number 1658?

To find the sum of the digits in 1658, we need to add the individual digits together. First, we break down the number: 1 + 6 + 5 + 8 = 20. Therefore, the sum of the digits in 1658 is 20.

Question: Suppose there are 1658 students in a school, and each student needs to form teams of 4 for a project. How many teams can be formed?

To determine the number of teams that can be formed, we divide the total number of students (1658) by the number of students per team (4). Thus, the calculation is: 1658 ÷ 4 = 414.5. However, since teams must consist of whole numbers of students, we round down the decimals. Therefore, a total of 414 teams can be formed from the 1658 students. By forming these 414 teams, all students will have partners to work on projects and contribute effectively. Creating teams promotes collaboration, diverse perspectives, and effective project completion. Furthermore, teamwork skills are enhanced in this process, helping students develop essential qualities for their future personal and professional lives.
