1. Find the value of (i) Absolute Value (a) ∣ 425 ∣ = 425 (The absolute value of a positive number is the number itself.) (b) ∣ − 618 ∣ = 618 (The absolute value of a negative number is its positive counterpart.) (c) − ∣ − 873 ∣ = − 873 -|-873| = -873 (First, find the absolute value of -873, which is 873, then apply the negative sign.) 2. Ordering Numbers (i) From smallest to greatest: -10, -8, 2, 5, 9, 16 − 10 , − 8 , 2 , 5 , 9 , 16 (Arrange the numbers in ascending order.) (ii) From greatest to smallest: 100, 0, -56, -181, -250, -300 100 , 0 , − 56 , − 181 , − 250 , − 300 (Arrange the numbers in descending order.) 3. Elevation Table Location Elevation (in m) P -205 Q 1200 R -1800 S 250 (i) Farthest from sea level: R (-1800 m) (The location with the largest absolute elevation value is farthest from sea level.) (ii) Nearest to sea level: P (-205 m) ...
