Absolute Value Write and explain

Question

Write the Absolute Value of each number and explain your reasoning

Answer 1

just change the sign if the number is negative, to make it positive, but keep the number the same otherwise.

absolute value of x = sqr(x^2) where you take the positive square root only

absolute value of -10 is +10,

absolute value of a positive number doesn't change anything, absolute value of +10 = +10
