ALGEBRA 1-2CHAPTER 1SECTION 1-5: ADDING AND SUBTRACTING REAL NUMBERSOBJECTIVE: To find sums and differences of real numbers.1)You can add or subtract any real number using a number line model. You can also add or subtract real numbers using rules involving absolute value.2) The absolute value of a number is its distance from 0 on a number line. Absolute value is always nonnegative since distance is always nonnegative.

3) The Addition of Rational Numbers Propertystates 2 things:a)To add rational numbers with the same signs, add their absolute values. The sum has the same sign as the addends.b)To add rational numbers with different signssubtract the lesser absolute value from the greater absolute value. The sum has the same sign as the number with the greater absolute value.,
