Use the digits 1,2,3 and 4 once each to get the largest answer possible

sukhopar [10]

Answer:

4,321

Step-by-step explanation:

This is the answer because:

1) We know that if the number has to be big therefore, we have to put 4 in the thousands place because 4 is bigger than 3, 2, and 1

2) Next, 3 is the other biggest number, for that reason 3 is in the hundreds place

3) Then, 2 is the other bigger number; therefore, the tens place is 2

4) Finally, the last number remaining is 1, which is in the ones place

Therefore, the answer is 4,321

Hope this helps!
