integers but can be represented on the number line. REAL NUMBERS Include all numbers that can be represented on the number line, that is, all rational and irrational numbers. ... Then add or subtract the numerators, keeping the denominators the same. For example,. 2 3 + 1 4 = 8 12 + 3 12 = 11 12 d Z 0 a d-b d = a-b d d Z 0 a d + b d = a + b d ...
