Math Question: If 213 is multiplied by the sum of its digits, divided by the difference between the tens digit and the units digit, what is the result?

To solve this, we start by finding the sum of the digits in 213, which is 2 + 1 + 3 = 6. The tens digit is 1 and the units digit is 3. Therefore, the difference between them is 1 - 3 = -2. Now, we multiply 213 by 6 (the sum of the digits) and divide it by -2 (the difference between the tens and units digit). Thus, the result is (213 * 6) / -2 = -639.

Question: If three equal numbers are multiplied and the result is 213, what is the value of each of those numbers? (Assume the numbers are positive)

Let's assume the three equal numbers are represented by x. According to the problem, x * x * x = 213. Thus, the equation can be written as x^3 = 213. To solve for x, we take the cube root of both sides: x = ∛213. Evaluating this cube root gives us x ≈ 6.16. Therefore, each of the three equal numbers is approximately 6.16.

Math question: If you divide the number 213 by the sum of its digits multiplied by the difference between its tens digit and units digit, what is the result?

To find the sum of the digits in 213, we add 2, 1, and 3, which gives us 6. The difference between the tens digit (1) and the units digit (3) is -2. Multiplying these two values gives us -12. Now, dividing 213 by -12, we get -17.75. Therefore, the result of dividing 213 by the sum of its digits multiplied by the difference between its tens and units digit is -17.75.
