A, B and C are three rational numbers which are not equal to zero. The product is negative and the sum is positive. Find the value of a | a | + B | B | + C | C | Sorry, it's a semicolon,

A, B and C are three rational numbers which are not equal to zero. The product is negative and the sum is positive. Find the value of a | a | + B | B | + C | C | Sorry, it's a semicolon,

Because the product is negative, one or all three numbers in ABC are negative
Because the sum is positive, only one number in ABC is negative
Then there is only one formula in a | a |, B | B |, + C | C |, which is - 1,
Then a | a | + B | + C | = 1
