## Algebra: A Combined Approach (4th Edition)

Answer : a) 7.2 b) 0 c) $\frac{1}{2}$
$\rightarrow$To find absolute value, just remove the sign in front of the number. $\rightarrow$If the number is negative, make it positive. $\rightarrow$If the number is positive, then let it remain as it is, just remove the positive(+) sign ( if any). $\rightarrow$ DO NOT change the number, remove only the sign. $\rightarrow$ eg. |-7.2| = 7.2 |0|=0 |-$\frac{1}{2}$| = $\frac{1}{2}$
