Math question: What is the sum of the digits of the number 486?

The sum of the digits of 486 is calculated by adding the individual digits together: 4 + 8 + 6 = 18.

Question: What is the value of 487 multiplied by 3, divided by 2, subtracted by 21, then divided by 2 again?

To find the value, we start with 487 and multiply it by 3 to get 1461. Next, we divide 1461 by 2 to obtain 730.5. Afterward, we subtract 21 from 730.5, resulting in 709.5. Lastly, we divide 709.5 by 2 to give us the final answer of 354.75. Therefore, the value of the mathematical expression is 354.75.

Math question: What is the cube root of 486 rounded to the nearest whole number?

The cube root of 486 is approximately 8. Since 8*8*8 = 512, which is greater than 486, and 7*7*7 = 343, which is less than 486, we round 7.87 to the nearest whole number, which is 8.
