Addition of Integers
Two positive integers always yields a positive sum; adding two negative integers always yields a negative sum. To find the sum of a positive and a negative integer, take the absolute value of each integer and then subtract these values.
Example: Add +6, +4
Solution: +6+4 = +10. Two positive integers always yields a positive sum.
Example: Add -4, -4
Solution: -4 + (-4) = -4 - 4 = -8. Adding two negative integers always yields a negative sum.
Example: Add +10, -4
Solution: +10 + (-4) = +10 - 4 = +6 . To find the sum of a positive and a negative integer, take the absolute value of each integer and then subtract these values.
Example: Mehak gives her friend Jenny Rs 135 and then she given Rs 100 to Rahul. Find total money given by Mehak.
Solution: Total Money given by Mehak = 135 + 100 Rs = Rs 235.
