Answer
The sum of 3 and -3 = 0
Step-by-step explanation
The sum of two numbers is the addition of both numbers.
Hence, the sum of 3 and -3 is written mathematically as
3 + (-3)
But we should also know that adding a negative number is the same as just subtracting that number
3 + (-3)
= 3 - 3
= 0
Hope this Helps!!!
