What is a negative plus a positive?
The knowledge of positive numbers and negative numbers is useful for the addition and subtraction of integers.
Answer: Negative plus positive is negative or positive depending on the magnitude of numbers.
Let's understand the negative plus the positive number.
Addition generally means to increase the value. But, in the case of integers, an addition operation might lead to an increase or decrease in the value of the given number.
If we add a negative integer, the value of the given number will decrease and if we add a positive integer the value will increase.
Addition of a positive number and a negative number:
- While adding a positive and a negative number, we take the difference of the absolute values of both the numbers and attach the sign of the greater number with the answer.
- a + (-b) = (a - b)
- 4 + (-5) = -1
- (-5) + 7 = 2
