Rules to Add and Subtract By
Rules for Adding and Subtracting Positive and Negative Values
 When we subtract a negative number we simply add the second number. Ex: 3 (6) becomes 3 + 6 = 9
 When adding, if the signs are the same, we add the numbers and keep the sign. Ex: 7 + 8 = – 15
 When we subtract a positive, we can modify the problem so that we add a negative. 2 5 becomes 2 + 5. Then we use rule number 2. Ex: 2 + 5 = 7
 When we are adding and the signs are different, we find the difference of the two numbers and keep the sign of the number with the greatest absolute value. Ex: 8 + 10. First we find the difference 108 =2. The answer is positive because 10 has a greater absolute value. The absolute value is the distance a number is away from zero on the number line.
