Solved Examples on Adding Negative Numbers
Example 1:
Find the sum of -6 and -10
Solution:
Given two numbers are -6 and -10
Sum = (-6) + (-10)
Sum = -6 – 10
Sum = -16
Hence, the sum of -6 and -10 is -16
Example 2:
Add the numbers 18 and -6
Solution:
Given numbers: 18 and -6
Sum = 18 + (-6)
Sum = 18 – 6
Sum = 12
Hence, the addition of 18 and -6 is 12.
Frequently Asked Questions on Adding Negative Numbers
Write down the rules for adding numbers.
Positive Number + Positive Number = Add (Put “+” sign)
Negative Number + Negative Number = Add (Put “-” Sign)
Positive Number + Negative Number = Subtract (Put the sign of largest number)
What is the sum of 15 and 20?
The sum of 15 and 20 is 35. Because the two given numbers are positive. Hence, we need to add two numbers with a positive sign
Find the sum of -7 and 10
The sum of -7 and 10 is 3. Here, -7 is a negative number and 10 is a positive number. So we need to subtract the given two numbers. So we get 3, and also the sign of the largest number (10) is positive. Hence, the sum is +3.
What is the sum of 1 and ½?
The sum of 1 and ½ is 3/2. Because 1 is a positive integer and ½ is a fraction.
= 1 +(½)
= (2+1)/2
= 3/2
Find the sum of 0.7 and 3/2.
Given two numbers are 0.7 and 3/2
Here, 0.7 is a decimal number and 3/2 is a fraction.
To add these two numbers, convert the fractional number into a decimal number.
So, 3/2 becomes 1.5
Therefore, sum = 0.7 +1.5 = 2.2
Hence, the sum of 0.7 and 3/2 is 2.2
