NEGATIVE OF AN ALGEBRAIC EXPRESSION

**Negative of an
Algebraic Expression **

**The negative of an algebraic expression is obtained by
changing the sign of each term in it.**

**Example – **

**1) If we multiply by the negative ‘-‘ sign to -4x + 3y – 8z, **

**Then, the result should be = - ( -4x + 3y – 8z) = 4x – 3y + 8z, where multiplication of two negative ‘-‘ sign
result count as positive ‘+’ sign and multiplication of one negative ‘-‘ sign
and one positive ‘+’ sign count as ‘-‘ sign.**

**2) If we multiply by the positive ‘+’ sign to -4x + 3y – 8z, **

**Then, the result should be = + ( -4x + 3y – 8z) = - 4x
+ 3y – 8z, where multiplication of two
positive ‘+’ sign result count as positive ‘+’ sign and multiplication of one
positive ‘+’ sign and one negative ‘-’ sign count as ‘-‘ sign.**
