Final answer:
To find the original number from which 10 is subtracted to get 23, you reverse the subtraction by adding 10 back to 23, which gives you 33 as the original number.
Step-by-step explanation:
To find a number where if 10 is subtracted the result is 23, you need to perform a simple addition operation. You will add 10 to 23 because subtracting 10 gave you 23, thus reversing the operation will give you the original number.
Let's do the calculation:
Start with the given result, which is 23.
Add 10 to this result to “undo” the subtraction: 23 + 10 = 33.
Therefore, the original number is 33.
