What is the sum of the digits of the number 3980?

The sum of the digits is 3 + 9 + 8 + 0 = 20.

Math Question: What is the sum of the digits of the number obtained by multiplying 3980 by its reverse?

For the number 3980, its reverse is 0893. Multiplying these two numbers gives 3980 * 0893 = 3556490. The sum of the digits in 3556490 is 3 + 5 + 5 + 6 + 4 + 9 + 0 = 32. Therefore, the sum of the digits in the number obtained by multiplying 3980 by its reverse is 32.

Math question: If the number 3980 is divided by 4, multiplied by 7, and then subtracted by 10, what is the result?

To find the result, we perform the calculations step by step. First, divide 3980 by 4 which gives us 995. Next, multiply 995 by 7 which yields 6965. Finally, subtract 10 from 6965 to get the result, which is 6955. Therefore, when we divide the number 3980 by 4, multiply it by 7, and then subtract 10, the result is 6955.
