Using two different digits from 0 to 9, what is the greatest two digit number that you can make
98
To find the greatest two-digit number using two different digits from 0 to 9, we need to select the highest digit for the tens place and the next highest digit for the ones place.
Starting from the highest possible digit, which is 9, we choose it for the tens place. Then, we select the next highest digit, which is 8, for the ones place.
So, the greatest two-digit number using two different digits from 0 to 9 is 98.
To find the greatest two-digit number using two different digits from 0 to 9, you need to look for the largest possible combination.
Here's how you can approach it step-by-step:
1. Start by listing all the available digits from 0 to 9: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
2. Since you need to use two different digits, you can choose the first digit from any digit other than 0. So, there are nine possible choices for the first digit.
3. For the second digit, you can choose from the remaining nine digits (including 0, if it wasn't chosen as the first digit).
4. Combine the chosen digits in the order that makes the greatest number possible. For example, if you choose 9 as the first digit and 8 as the second digit, the greatest two-digit number you can create is 98.
5. Repeat this process with all possible combinations to find the greatest two-digit number.
To summarize, the greatest two-digit number that you can make using two different digits from 0 to 9 is 98.
