take any negative number, and subtract a positive number..that is the same as adding a negative number and two negative numbers added together are a negative number.
There is no such number.
The least number is -6710. That gives the sum as 6710 + (-6710) = 0, which is a perfect square.The least positive number is 14.
To find the number that, when added to a certain number, equals 46, you would subtract that number from 46. In this case, the number would be 46 minus the given number. For example, if the given number is 20, then the number that, when added to 20, equals 46 would be 46 - 20 = 26. Therefore, the number that, when added to the given number, equals 46 is 46 minus the given number.
