The absolute value of a number is equal to the opposite of the number. Such a number is ()


Non positive number



If the absolute value of A-1 + the absolute value of B + 3 = 0, then what is the value of b-a-half


|a -1| + | b +3| = 0 ==> a - 1 = 0,b + 3 = 0 ==> a = 1,b= - 3 b -a - 1/2 = -3 - 1 - 1/2 = -9/2



Absolute value of X-1 + absolute value of X-2 + absolute value of x-3


The answer is - 3x + 6 or 3x + 6 or 6, because when x is negative, the absolute value is equal to the opposite number, then the original formula = - x + 1-x + 2-x + 3, the result is - 3x + 6; when x is positive, it is equal to itself, the sign remains unchanged, the original formula = X-1 + X-2 + x-3 = 3x + 6; when x is 0, the original formula = | - 1 | + | - 2 | + | - 3 | = 1 + 2 + 3 = 6
