SOLUTION: find the value of expression:2*|-5|

Hi

find the expression:  

  2*|-5| = 2*5 = 10

Note: |-5| read as the absolute value of -5 is a measure of the 'numerical value

of a number' without regard to its sign. that is |-5| = |5|

(can be thought of the distance of the number from zero on the number line)
