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.

From the number line: Look at the number line below. If we start at 0, and move 3 to the left, we land on -3. If we then move another 6 to the left, we end up at -9.
