Math question: What is the sum of the digits in the number 626?

To find the sum of the digits in 626, we can individually add the digits together. 6 + 2 + 6 = 14. Therefore, the sum of the digits in the number 626 is 14.

In a middle school, there are 626 students in total, and they are divided into 3 equal sections for a competition. If each section needs to have an equal number of students, how many students will be in each section?

The problem can be solved by dividing the total number of students, 626, by the number of sections, which is 3. Dividing 626 by 3 gives an answer of 208 R2. Since we cannot have a fraction of a student, the 2 remaining students will be assigned to one of the sections, resulting in 209 students in each section.

If 626 is divided by 2 and then subtracted by 50, what is the result?

To find the result, we divide 626 by 2: 626 ÷ 2 = 313. Then, subtract 50 from 313: 313 - 50 = 263. Therefore, the result is 263.
