Adding and Subtracting Negative Integers cf.ltkcdn.net
Apply addition and subtraction of integers to a problem-solving project. This lesson is designed for Sixth and Seventh Graders. Addition of Integers. When integers have the same sign, add the integers. The sum will have the same sign as the integers. + 7 + + 8 = + 15 -9 + -4 = -13. When integers have different signs, find the difference between the two numbers. The sum will have the …... There are a few key methods to add and subtract integers. The first is easy to use but takes more time and thought (less automatic with practice). It is the number line method. Imagine (or draw!) a number line with 0 at the middle and negative numbers extending to the left. Now when you add a number, go to the left if it is negative and the right if it is positive to arrive at the answer. When

- Example $$ -4+(-3)=\, ?$$ We always start at zero. Our first number is negative four (-4) so we move 4 units to the left. We then have plus negative three (-3) which is the same as subtracting 3 so we move 3 more units to the left.
- Adding and Subtracting Integers -. to add integers with the same sign, add their absolute values and then change the sign to the sign of the addends. positive if both integers are positive negative if both integers are negative. addend.
