Math question: If 813 is multiplied by 9 and then divided by 3, what is the result?

To find the result, first multiply 813 by 9, which gives you 7317. Then, divide 7317 by 3 to get the final answer. The division yields 2439. Therefore, the result of multiplying 813 by 9 and dividing by 3 is 2439.

Math question: If the number 813 is multiplied by 3, then divided by 9, and finally added to itself, what is the resulting value?

To find the resulting value, let's calculate step-by-step. Step 1: Multiply 813 by 3, which gives us 813 x 3 = 2439. Step 2: Divide 2439 by 9, giving us 2439 ÷ 9 = 271. Step 3: Add the initial number 813 to the result of step 2, so 813 + 271 = 1084. Therefore, the resulting value is 1084.

Math question: What is the sum of the digits in the number 813?
